Just like the rest of your vehicle's major systems, the cooling system must also be addressed periodically to ensure proper cooling and component reliability. Plastic and rubber components become brittle and prone to splitting or cracking after long periods of heating and cooling cycles, especially in colder climates! The coolant itself can degrade or become contaminated, leading to potential corrosion or freezing issues. Finally, thermostats and sensors can fail completely, preventing proper cooling and/or coolant temperature readings to become inaccurate.
To make sure you are not left stranded on the side of the road with an overheated engine, we have put together this Basic Cooling System Service kit. This kit contains all of the most-likely-to-fail components, giving you peace of mind knowing your engine will continue to run cool for another 60,000+ miles.
See kit contents below for all included components.

This brake package for the 2001-2006 BMW E46 M3 ZCP (Competition Package) comes with everything you need to perform a major brake overhaul -
Front and rear rotors with hardware - Genuine BMW replacements
Front and rear brake pads - OEM organic, street performance, mixed track/street, or full race
Front and rear pad wear sensors
Brake fluid - DOT4 street or DOT4 racing fluid
Our brake package uses the same replacement parts from the same manufacturers as BMW dealers use to service your car. The big difference is that we're able to offer these parts for a substantial savings from the dealer markup price. As an independent company we're able to buy our parts from multiple OEM suppliers whereas BMW dealers must buy their parts from BMW. We're able to shop from different vendors which gets you a better price while still maintaining original quality. You don't have to pay high prices at the dealer to get the same quality and performance!
In some cases, we offer performance alternatives to the OEM items. For an enthusiastic BMW owner, the standard BMW part may be inadequate and we offer an upgraded part, based on our almost 20 years of BMW tuning experience. We seek out high quality suppliers and designs that we would want on our own vehicles. Many times performance parts will fix a design flaw with the original BMW part, improving your performance at the same time.
This kit is a direct replacement for the standard floating and cross-drilled 345mm rotors in the ZCP Competition Package. This is brake overhaul for the ZCP and will not work as an upgrade for non-ZCP unless the ZCP front caliper brackets are used. We offer the full E46 M3 ZCP brake upgrade on the website here (click).

Shark Injector Performance Software
The enthusiast's choice for over a decade, the Shark Injector's performance is only equaled by its own ease of install! Tune your ECU at the press of a button simply by plugging into the under-dash OBDII diagnostic port, there is no removal of your car's computer; no laptop or cables required. What does the Shark offer?
Turner Motorsport Power Pulleys
Underdrive Power Pulleys work to 'free up' horsepower. Any accessory that spins from the main drive belt is using up power. That's power that could otherwise be used to move the car. By giving some of that power back to the engine, you can make the car faster! We measured 10.7 whp at 6960 rpm and 8.1 lb-ft of torque at 5550 on a 1995 M3. Race pulleys deliver even more power.
Another "no-downside" upgrade, we even include a new belt. Total install time for a 3-piece pulley set should be around 1.5 hours. We offer three options in pulleys:
1.) No alternator pulley included - for cars with big amps and powerful stereo systems that need the extra juice.
2.) Street Power Pulleys - our most popular option with no downside!
3.) Race Power Pulleys - delivering 15 "free" horsepower, this set underdrives the water pump, power steering pulley, and alternator for lower temps, less wear, and more power. Not for street use.
Intake Air Temperature Relocation Kit
Looking to maximize your power gains? Add a Turner IAT Relocation to combat power-robbing heat soak - the only true plug-and-play solution available. Heat soak is a real plague on consistent power for a stock or tuned vehicle. Click here to read more about our IAT relocation kit.

This package allows you to build your own rear bushing package to cover the parts you want to replace. As these cars age, they require a number of suspension bushings to be replaced. Bushing replacement not only keeps the car in its top form, it also makes the car safer. Depending on the work, it may be logical to replace all of the bushings in the rear suspension (there are 19 total). This is especially true if you are pulling the subframe out to do the floor reinforcement or if you're doing a diff install. Turner Motorsport is a big believer in using rubber bushings for street cars (with the exception of solid subframe mounts, see further below). Urethanes, Delrin, or aluminum are generally good for reducing compliance and limiting deflection - attributes that don't really work well on roads filled with potholes, railroad crossings, cracks, and expansion joints. The rubber bushings maintain the factory ride/handling traits that won the M3 praise all over the world. Every bushing will need maintenance or replacement at some point and rubber has proven to last the longest and need less maintenance than anything else, even urethane. And unless competitive driving is your goal, the harder materials are only a gimmick.
Any major overhaul of the rear suspension should include new subframe mounts. The worn rubber mounts contribute to rear subframe-floor failure when the deflection in the mount is transferred to the chassis. Rubber mounts are only OK for street cars that don't see aggressive driving, autocross, or track use. For any enthusiastic driving, we strongly recommend our solid aluminum subframe mounts even on the street. They have zero deflection and will not contribute to rear floor failures. And if you leave rubber in the rest of the suspension your ride comfort will not suffer.

Take the guesswork out of S54 ownership. This all-inclusive kit targets the two most notorious failure points on the BMW S54 engine: broken exhaust hub tabs and degraded internal seals.
Turner Motorsport S54 VANOS Exhaust Hub Upgrade
The factory S54 exhaust hub is a ticking time bomb. Excessive play between the drive tabs and the oil pump disk creates a rhythmic rattling that eventually shears the tabs off, risking catastrophic engine failure.
While other kits require deep-engine surgery, our Turner Motorsport Hub Upgrade offers a "work smarter" approach.
Precision Engineering: Developed using 3D scanning and CAD modeling for a perfect, interference-free fit.
Superior Materials: Machined from high-strength 4340 steel and hardened to OEM specifications.
No Re-Timing Required: This bolt-on fix eliminates the failure point without the need to disassemble the VANOS unit or disturb engine timing, saving hours of labor.
ECS Tuning VANOS Seal Kit
The original BMW seals are made of Buna-N rubber, which quickly hardens and loses its sealing properties when exposed to synthetic oil and high heat. Our ECS engineering team has corrected this flaw.
Viton Upgrade: We utilize high-performance Viton O-rings for the internal seals, seal plate, and solenoid.
Chemical Resistance: These seals are designed to remain pliable and effective for the life of the engine, restoring lost low-end torque and smoothness.
ECS Tuning Rattle Repair Kit
Eliminate the dreaded "marbles in a can" sound. This kit addresses the axial play in the VANOS helical gears.
Hardened Steel: Our rings and washers are precision-ground to resist the wear and deformation that lead to engine rattle.
Silent Operation: Restores the refined sound and feel of your S54 across the entire RPM range.

As the E46 M3 gets on in years and mileage, the cooling system will be one of the areas that needs the most attention. We have packaged all of the major cooling components into one overhaul kit:
We have found that the E46 M3 can develop inconvenient cooling issues, even on daily driven street cars. While the infamous radiator and water pump failures of the E36 are a thing of the past, the E46 M3 still has its own complications. The best approach to avoid bigger problems is preventative maintenance. We recommend replacing the water pump before 80,000 miles and the radiator before 100,000 miles. By addressing these problem areas before a failure, you will save yourself a larger repair bill in the future.
In addition to the standard cooling package items above, there are several other cooling-related components that may make sense to do at the same time:
This cooling overhaul package fits:
2001-2006 E46 BMW M3
