Replace the Achilles heel of your factory cooling system with a stout and reliable mechanical thermostat setup.

The factory E46 thermostat housing is a combined unit featuring a plastic housing and a built in thermostat that you cannot replace separately. These plastic all-in-one units are commonly know to crack or fail causing a headache, a trip on the tow truck and possible damage to your engine.

Taking cues from the reliable M50 thermostat setup we designed a an assembly that not only converts your plastic housing into a billet aluminum unit but also swaps out the integrated thermostat for a separate replaceable thermostat. The ability to swap out thermostats separately from the whole housing opens up doors to changing thermostats to different temperature ratings based on your application while also providing lower maintenance costs. No longer do you have to replace the whole housing but just the thermostat itself.

The billet housing is designed to be utilized with E46 M3 upper and lower radiator hoses and also features -16 ORB connections for custom radiator hoses. A major upgrade from the factory and aftermarket plastic units. Our thermostat housing kit can be used by the savvy daily driver or the track hero who wants to ensure the durability of their cooling system.

Key benefits:

Uses M50/S50 mechanical thermostat for increased reliability
Option to use aftermarket colder thermostats if desired
Thermostat can be replaced separately for lower maintenance cost
Barbed hose connections for use with E46 M3 hoses or built in -16 ORB connections for custom radiator hoses
Design:

Machined out of a single piece of billet 6061 aluminum, this thermostat housing will withstand higher prolonged temperatures and abuse for performance applications
Black anodized with engraved Turner logo on the front to match the Turner Motorsports Power Steering Reservoir
Viton gasket for superior sealing performance
For use with E46 M3 radiator hoses 11537830715 and 11537830716
Kit contents:

6061 Billet Aluminum Thermostat Housing
Mechanical Thermostat
Thermostat Housing Gasket
Thermostat Harness
Optional Silicone or Rubber E46 M3 coolant hoses
Product Development:

Our Billet Thermostat Housing upgrade was designed, engineered, tested and quality inspected by our Research and Development team at Turner. Nothing but the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer and rigorous long term product testing.

Lightweight performance exhaust for your E46, featuring a valved muffler and controller to change the sound with the click of a button.

When it comes to shopping for exhausts you want to find one that suits your driving style and sound preference. While one part of you wants to have a loud and aggressive sounding exhaust, there is another part of you that knows you don't want to wake up the neighborhood or annoy your significant other. Finally the answer to your dilemma, thanks to our engineers at Turner you no longer need to choose between rowdy and tame. With your new light-weight performance exhaust you have the option to go from tame and tasteful to loud and rowdy.

Our Valved exhaust was designed specifically for your E46 and there are no other options on the market like this. Control the tone and volume of your exhaust with the click of a button. With the valves closed you have a nice low tone and hearty exhaust note. When the valves are open you get complete unrestricted access to sound and power for when your at the track or just in the mood to let it rip.

Our Turner catback features dual 2.0" stainless steel mid-pipes that connect directly to your factory downpipes. Within the mid-pipes is an integrated x pipe for a smooth flowing center section with lower amounts of back pressure which leads to increased performance and a smoother exhaust tone. The 2.0" mid-pipes crossover and flow into a 3" exhaust section and full 3" valved muffler. The muffler features integrated 3" exhaust tips for an aggressive look that fills out your rear diffuser to get the perfect appearance.

Valved exhausts of this caliber can be found on new performance models, super cars and overall cars way above the price ranges of a nice E46. Surprisingly enough some E46's did come with a type of vacuum actuated mufflers which opened and closed the exhaust under certain rpm ranges, unfortunately by now the factory valve is damaged or the muffler no longer actuates. Although the factory valved muffler on E46's were great in theory, there was very little change in tone and was limited by your driving style. Taking notes from the original engineering process from BMW, our engineers revitalized this cool technology and made it better. The final product is a light-weight performance exhaust that features superior valving and show stopping aesthetics!

Free-flowing intake featuring a roaring induction noise and increased performance to replace your restrictive factory intake.

Upgrade your E46 driving experience by adding induction noise and increased air flow. Let your engine breath and listen to the sweet sweet intake sounds!

With the factory intake you are limited to a finite amount of air, this leaves your engine under-served and limits induction noise. When it comes to the recipe for upgrading your E46 there are a few ingredients that you must have, power and sound. While you can add an exhaust for a bit more power and sound, the biggest difference you can make is adding power and sound under your hood with a high-flow intake. The factory intake box is also referred to as a silencer specifically designed to lower the induction noise for a refined driving experience, this helped exponentially when selling the cars out of the show room circa early 2000's. We as enthusiasts are no longer interested in subdued intake noise and limited air-flow, we want pure induction noise, we want to hear the air being sucked into the engine as we push down on the accelerator.

Key benefits:

Flows on average 71 CFM more than the stock intake system, a ~27% increase in intake efficiency
Increased induction noise
Maintains factory air induction track
Maintains Stock MAF location, allowing user to switch back to the stock airbox and retain the ECS Silicone boot if desired
Design:

Durable, lightweight 6061 and 5052 aluminum intake tube and bracket design, finished in wrinkle black powder coat
Mounts to locations on chassis utilizing Stainless Steel M6 hardware
MAF mounts to intake using aluminum brackets sealed to intake system with OEM fitment
Maximizes available engine bay space to fit oiled ECS cotton gauze 7” filter
Silicone intake boot with improved flow characteristics replaces failure-prone facotry accordion intake boot with provisions for F-connector fitting and Idle Air Control (IAC) valve inlet

Looking for coilovers that will provide reliability on street driven vehicles but are also capable of feeding your weekend track demon's desire for performance? BC Racing's BR Series coilover kit may be just the thing for you.

BR Series coilovers are the most popular and versatile option offered by BC racing, offering features such as 30-level dampening adjustment (simultaneous compression and rebound control), linear springs where possible, and a minimum of 2 inches ride height drop. To ensure performance, comfort, and quality, all BR Series kits are Dyno tested during the design stage to determine the best valving and spring rates, then installed and tested for a minimum of 6 months. This kit features mounts and brackets that are fully compatible with all stock mounting points and components.

The upper shock/strut mounts are all constructed of 6061-T6 Aluminum for strength and weight savings. BC Racing design 1 of 3 types of upper mounts for each vehicle: Caster/Camber Plates (+/- 3* camber), Camber Plates (+/- 3* camber), and Rubber Mount Plates (NVH reduction). The included mount option for this kit is shown in the kit specs and features below.

Lower shock mounts are powder coated for corrosion protection and constructed of either 6061-T6 aluminum that has been milled from a single piece (fork or bolt eye mount) or of STKM13C steel with all brackets welded robotically.

The included springs come in one of 3 styles: linear, S-barrel, and V-barrel. Linear springs are used in most applications unless limited by the OE design that does not allow the use of linear springs. All spring options are made from SAE9254 steel and have a zinc coating applied under the powder coating for increased spring corrosion protection and long term reliability.

All shock bodies used in the BR Series coilovers use a 53mm shock body (unless noted otherwise) for added strength, performance, and increased fluid capacity. All shocks are then powder coated black chrome for clean styling and corrosion protection.

Specs and Features:

  • 8k Front & 12k Rear Spring Rate
  • Linear front & S-Barrel rear springs
  • Valved specifically to spring style and rate
  • Camber Plate Front Mounts
  • Aluminum and Rubber Rear Mounts
  • Black Powder Coated Components
  • All OE style brackets and mounting for perfect fit
  • 30 Levels of Simultaneous Compression and Rebound Dampening
  • 2 inch minimum and 3+ Inches of total potential drop
  • Great for Track, Street, and any other conditions

Bilstein has teamed up with Eibach to offer matched shock and spring packages. These Eibach springs are mated to a special set of Bilstein shocks to deliver a sporty and taut ride with as little impact on ride comfort as possible.

The Pro Kit uses an Eibach Pro Kit spring with Bilstein's Sport shocks and struts. Instead of taking parts from different manufacturers, Bilstein has tested the performance of the Eibach spring and tailored their shocks to be a true match for the new spring rate and ride height. This is known as a matched shock and spring and very few tuning companies take these extra steps. Eibach springs tend to be softer overall than most other aftermarket springs, which ensures the ride stays close to a stock comfort while still giving you a lowered stance and improved handling. 

Bilstein B12 Features: 

  • Precise response and excellent driving performance
  • Springs and shocks road tested and fine-tuned to complement one another
  • Bilstein Monotube/Inverted gas pressure technology
  • TUV certified
  • Made In Germany
  • Average Lowering of 25 to 40mm

Most cars don't need coil overs to improve their handling and bodyroll. For most drivers, simply replacing the shocks and springs with performance versions will meet their goals. If your shocks need replacing, and you felt the handling could be improved a little bit, this is an excellent performance suspension for you.

This item fits the following BMWs:
1999-2006 E46 BMW 323/325/328/330i/ci

The Carbon Fiber ECS strut tower bar kit offers more than just good looks - it also serves to protect strut towers from "mushrooming" or other deformation caused by rough roads or vehicles with stiff suspension and helps to triangulate the front end, providing more consistent suspension geometry with less chassis flex. Strut tower plates should sit flush against the strut towers. If this is not the case, your strut towers are to some extent deformed. This can be easily remedied in minor cases with a block of wood and a hammer. Carbon fiber is an excellent addition to any vehicle and offers a very unique look that is found on some of the most exotic vehicles on the road today. This strut bar kit features a clean woven design that is sure to look phenomenal for years to come and will compliment absolutely any engine bay. Don't settle for a boring stainless steel or aluminum strut bar, your BMW deserves the best. Features high gloss carbon fiber bar and black CNC machines tower plates with stainless steel hardware. Not for SULEV M56 engine models.

Our experience with spherical front control arm�ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).��We wanted to offer e30, e36, and e46 owners similar levels of handling precision and control for the track and street, but weren�t satisfied with the other options out there.� Instead of a Delrin bushing or unsealed spherical bearing alone, we selected an oversized sealed greaseable spherical monoball to offer unparalleled durability and precision, but designed a Delrin adapter sleeve to help isolate the added noise, vibration, and harshness that a full solid monoball bearing will have.�While race-ready,�our hybrid Delrin/monoball control arm bearings are more at home on the street than other kits that are advertised as��race-only� bearings. We did extensive street, autocross, and track testing to ensure the spherical bearing used in this bushing design excelled in each setting.

The stock rubber bushings, even�those found in the M3,�allow significant fore/aft movement of the front wheels to help absorb road impacts, especially when being pushed hard. �This soft flexible design maximizes daily driving comfort, but also allows considerable alignment change.� This unwanted deflection�stands between you and a crisp, confidence-inspiring driving experience. �The advantage of a monoball bearing is that it will not deflect under load, eliminating all unwanted deflection while still allowing�complete freedom of movement�in the desired angles. What you get is superior steering precision with better handling from more consistent alignment�and direct braking feedback, with exceptional service life.� Thanks to the�Delrin insert and double lip seals, there's none of the extra noise or reduced service life�often�found on�other�spherical bearings.

In short, if you're seeking front control arm bushings that offer precise, predictable handling, crisper braking feel, with a long service life free from noise - look no further. We have you covered.

Features:

Bearing housing

  • Manufactured using 6061-T6 blue anodized aluminum with a pre-installed grease fitting and grease distribution channels making this a serviceable design
  • Knurling allows for a wide variance in lollipop dimension, although this particular SKU comes pre-installed, so you won't need to worry about that.�Want to install your own? Click here.

Bearing

  • A high quality greaseable double lip sealed bearing with Delrin� inserts. Delrin� was chosen due to durability�under pressure, while still soft�enough to create a perfect play-free fitment on the control arm.
  • Replaceable for infinite service life - no need to replace the entire mount in the event a bearing happens to fail.

Includes new hardware. Grease before installation and with each oil service with high quality Moly grease for maximum service life.�Need a grease fitting tool?

"Oil-Free" ProDry S Filter

This intake kit replaces your restrictive factory air box. It features a 3-angle aluminum velocity stack adapter, 1.6mm powder-coated steel heat shield, trim sealed to seal out hot engine air, and a custom aFe brand cotton filter.

This version has an oil-free filter media for less maintenance. For the best flowing filter, with the best performance gain, we always recommend the standard aFe "Pro5R " filter (which has a blue pre-oiled filter media), but this oil-free filter flows only slightly less than the blue Pro5R style aFe filter, and requires no re-oiling after cleaning the filter.

By removing your stock intake air box, you are removing the most restrictive portion of your intake system, increasing both horse power and torque, improving acceleration as well as throttle response.

aFe has reported gains as high as 20 hp and 27 lb/ft torque on the 330i

For the maximum benefit in performance, we recommend upgrading your engine software with the Shark Injector (Click here for more info on the Shark Injector performance software.)

This aFe intake fits the following BMWs:
2003-2006 E46 3 series : BMW 325i 325ci 325xi + Wagon & Convertible models with M56 engine
2001-2006 E46 3 series : BMW 330i 330ci 330xi + Convertible
2004-2007 E83 X3 : X3 3.0i

Clickhere for installation instructions.

Want an extra layer of defense? Add a pre-filter to prevent water, mud and sand from congesting your air intake system. This simple upgrade slides over the aFe filter of this intake kit, much like a sock, giving you an extra layer of defense, and extending the cleaning interval of your aFe intake's filter element. Best of all, using the Pre-Filter does not significantly diminish your air filters performance the smooth rush of oxygen keeps rolling right into your engine.

Dinan has enigneered a new air box cover that allows  you to run a larger air filter but retain a stock-like appearance. The Dinan 330 intake cover seals better to the lower section ensuring no power-robbing hot air enters the intake. A new lower tube draws air from the brake duct, nearly doubling the volume of cool air entering the engine.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere.

Why is SFI testing and certification important?

The SFI Foundation, Inc. (SFI) is a non-profit organization established to issue and administer standards for the quality assurance of specialty performance and racing equipment. SFI certification indicates a flywheel has been certified using industry-standard SFI Spec 1.1 standards by an independent testing body to ensure quality of both design and materials for flywheels utilized in competitive motorsports.

Having successfully passed SFI certification, this flywheel has an individual SFI serial number found in a laser etching, and on an affixed sticker. This certification means the ECS-engineered flywheel is safe and reliable during the rigors of competitive racing; it's also safe and reliable for years and years of street use.

Worn rubber differential mounts will lead to the differential twisting and shifting around in the rear subframe. Not only will this be noisy but it's bad for driver confidence and bad for the chassis as well. Even on fresh rubber bushings the differential has deflection and twist, especially if the car has been modified for more torque. Since the differential is centrally mounted in the rear subframe, with all suspension mounts interconnected, a differential with too much deflection will affect handling and could even damage the rear subframe.

These 88A urethane E46 diff mounts are much stiffer than stock but still not as solid as our Turner aluminum/Delrin bushings. This set will resist twisting much better than the stock rubber mounts. Included are the two front diff mounts and the rear mount in the cover.

Updated in 2020 to provide additional reinforcement! The E46 rear driveline and suspension are very similar to that of the E36. An unfortunate side effect of this is that the E46 also shares some of the same problems as the E36. One of these problems is the rear mounting points for the subframe, which can rip out from their spots in the sheet metal. This happens because the rear differential transmits the torsional load from the engine through the subframe, then into the chassis. This constant loading and unloading weakens the sheet metal and causes it to fatigue and separate from the chassis. BMW tried to fix this problem in the E46 by placing a cross member on the front two mounting points of the subframe. This cross member keeps the front mounting points from having problems by placing the bushing and the stud in double-sheer, thus reducing the twisting action on the sheet metal. The unfortunate side effect of this is that the load from the front of the subframe now gets transmitted to the left rear of the subframe. This is where we have seen many failures of the chassis on low mileage street cars and race cars. BMW has also tried to prevent the issue by injecting foam into the open space between the underside of the chassis and the top of the trunk. This seems to work but that does not address the issues of the spot welds failing on the sheetmetal. It can also make any additional work there harder and almost impossible to weld against. Our reinforcement kit has proven over and over again to be effective and the easiest to work with in the long run.

This product reinforces the chassis sheet metal at the subframe mounting points. We do this by thickening the metal and distributing the load over a larger area. This kit will save time when repairing the chassis, and is also strongly recommended as a preventative maintenance item.

  • Rubber isolated for reduced NVH
  • Maintains stock shift feel with uprated stock-type bushings

The Dinan short shifter provides shorter shift throws with a crisper and more precise feel than a stock shifter. Instead of retrofitting a stock BMW lever, with all of its deficiencies, Dinan has engineered this billet aluminum shifting system. Special features engineered into this unit include a two piece fully isolated stick assembly, exclusive integrated and dampened pivot cup with self lubricating pivot ball, counter balanced to reduce effort and exclusive polymer "Iglide" T-500 lower pivot bushings that are impervious to contamination. Featuring an adjustable pivot, which allows this shifter to fit both standard and M Series applications. All of this combined with a simple straightforward installation provides a professional level shifter. Provides a 25% throw reduction in E36s, E39s and E46s and a 20% throw reduction in M3 and M5 applications.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty.

Gain a significant competitive edge with the MFactory Helical Limited Slip Differential, available at Turner Motorsport. This Helical LSD delivers a smooth and consistent distribution of power to your BMW's wheels, optimizing traction on the street, strip, or track. It's an essential addition for any BMW enthusiast.

Curious about the LSD's role? Without it, your car effectively becomes a one-wheel-drive vehicle, supplying torque to the wheel with less grip. The Helical LSD changes the game by allowing both wheels to receive power while limiting the speed difference between them, in contrast to open differentials commonly found in most vehicles.

Key Features:

  • 30-Day Feel the Torque™ Money Back Guarantee: An industry-first assurance that lets you experience the difference. Plus, it's backed by a Limited-Lifetime Warranty for your peace of mind.
  • Forged and Cryo-Tempered: Engineered for extreme durability and longevity, ensuring it can withstand the rigors of competition-level drag racing.
  • Advanced Shot Peening Technology: Enhances surface hardness, making it well-equipped to handle the shocks of competition-level drag racing.
  • Maintenance-Free Gears: Bid farewell to special fluids or rebuilds associated with typical plate LSDs. It's designed for hassle-free ownership.
  • Lock-Free Operation: Ensures there's no adverse impact on steering response.

Break-In Procedure: For optimal performance, it's recommended to change the fluid after the first 3-400 miles of use.

Please note that any defects or warranty claims should be directed to Team MFactory.

The E46 Non-M RWD belly pan is a constant point of impact for parking curbs, inclines, and road debris. Fortunately, there is usually little damage other than the brittle belly pan plastic and side covers, which is still not a cheap expense. The Turner Motorsport skid plate is the ultimate upgrade for your belly pan replacement woes, eliminating all common issues experienced with the stock plastic belly pan. We wanted to offer something that would protect all of the underside engine components, on both streetcars and modified track cars, as you never know when something will pop up on the street or track. Something as mundane as a parking block or roadkill can damage a plastic belly pan - we’ve all seen drooping, damaged belly pans, and the resulting filthy engine bays. Even though the stock plastic belly pan and this skid plate look similar, there are a lot of features taken into consideration when this was designed. The plates mount slightly higher offering even greater ground clearance so there is less chance of impact, even though this skid plate will provide all the strength you need to feel safe! Manufactured from 1/8" 5052 Aluminum and mounted to your RWD E46 with the included brackets and hardware, this skid plate integrates perfectly with the factory plastic liners and mounting points without any major modification necessary for installation.

There's something about a High Kick Trunk Spoiler that makes an E46 Coupe look even better! Going off of our design from our original Carbon Fiber High Kick Spoiler, we have developed an ABS High Kick Trunk Spoiler that transforms the look of your E46 coupe, all while keeping budget constraints in mind. Constructed from impact and UV resistant ABS plastic, this light and durable spoiler provides a sporty style that's sure to set your vehicle apart from the rest, without the high price of an equivalent carbon fiber spoiler. Installs with no drilling, cutting, or any permanent modifications! Included are two pre-mounted double side adhesive strips for easy installation onto your trunk lid. Simply clean the surface area of the trunk, remove the backing from the already attached high strength double-sided tape, line it up, and press firmly down. We recommend doing this in a warm environment as it will better adhere to the trunk. Features & Specifications: Designed and engineered by Turner Motorsport in-house using state of the art 3D laser scanning and CAD technology for precision fitment. Mimics the design of our carbon fiber version as closely as possible for similar styling. Accentuates the OE body lines throughout the outer edge of the spoiler Utilizes 3M double-sided tape for a strong bond to the body Made from lightweight, vacuum-formed gloss black ABS polymer that is enhanced with UV-stabilizer

The E46 M3 CSL sparked a lot of interest among enthusiasts about the "high kick" look. But what about those who want the aggressive, high kick look without having to replace the entire trunk? We found ourselves scratching our heads, especially unsatisfied with the add-on CSL spoilers you can find on the market.

We took it upon ourselves to CAD design an aggressive, high kick spoiler that pays homage to the CSL trunk, while flowing perfectly with the simple, yet aggressive body lines of the E46 coupe. The carbon fiber is hand laid, with a beautiful gloss finish that will match well with any other carbon fiber accents on your E46 coupe. Our high kick rear spoiler will instantly give your vehicle a more aggressive look.

These 2-piece floating rotors help dissipate heat better than a standard cast iron rotor and are also lighter for less unsprung weight. Managing heat in the brake system is vital to braking performance, especially on the track or when driven hard. It's why your brake rotors have internal vanes that vent heat as the rotor spins. These 2-piece ECS rotors feature an outer cast iron friction surface ring that is separate from the aluminum center hat. This allows better airflow through the vanes and for the friction ring can expand as it gets hot. The rotors are also cross-drilled for better ventilation and slotted to improve brake pad performance.

ECS 2-Piece Rotors feature:

  • Aluminum hats for light weight
  • Heat-treated cast iron friction rings
  • 2-piece assembly improves brake cooling
  • Anti-corrosion coating on non-friction surfaces and hard anodizing on rotor hat

These are the same size as the stock rotors so your stock caliper and mounting bracket will fit and there will be no clearance issues with your wheels or to other components. Stainless steel rotor retaining screws are included. You can use these with any brake pad.

Price is for the pair of brake rotors.

This item fits the following BMWs:
2001-2006 E46 BMW 330i 330ci 330xi
2006-2008 E85 E86 BMW Z4 3.0si

ECS Exact-Fit stainless reinforced brake lines ensure consistent and reliable stopping power - ECS's stainless steel lines help maintain consistent brake pressure, while capitalizing on the inherent benefits of stainless steel. If you are already planning on replacing your factory lines due to your vehicle's age, ECS's stainless steel brake lines are a great solution. Factory rubber lines expand under heavy braking, even when new. This causes sloppy pedal feel and overall poor performance. ECS reinforces their exact fit lines with braided stainless steel mesh, creating expansion resistance - this enhances pedal feel and improves performance. Their red polymer coating provides protection from the elements and abrasion that commonly affect brake lines. ECS Exact-Fit stainless lines are manufactured to comply with DOT (U.S. Department of Transportation) FMVSS 106 standards. All lines are made on dedicated, DOT-compliant brake equipment, with every line being tested to 3000 psi prior to shipment.
