Peak Power Gain: +15hp / +10ft-lbs
Rev limit: 7000
Octane: 91 or higher

Our Stage 1 kit featuring a cold-air intake kit and performance software. The aFE intake is made from high-quality materials, reducing underhood temperatures and not contributing to heat soak of the air filter. aFe's Stage 2 Intake uses an oiled cotton air filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, ABS plastic intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

Both of these items work together to bring up huge torque increases and much improved driveability. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice.

Tensioner Pulley for Main Drive Belt (Water Pump/Alternator/Power Steering) (more info)

This is the tensioner pulley, also known as the adjusting pulley and lower pulley. This pulley is mounted on the belt tensioner near the center of the belt assembly. The upper and lower pulleys are known to be the primary sources for 'belt squealing'. This pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).

This pulley is mounted along with the hydraulic or mechanical belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time.

Cylinder Heads

ARP S54 Head Stud Kit (E46M3 / MZ3 / MZ4) (more info)

Virtually every top professional BMW engine builder relies on ARP Pro Series head studs, particularly on the S54 3.2 liter engine. ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Each stud is heat-treated to 200,000 psi, ensuring complete heat penetration. ARP studs are threaded after heat-treat, which gives them 1000% (that's ten times!) better fatigue strength than studs threaded prior to heat-treat. Threading the studs after heat-treating is more difficult and costly (as it's harder on tooling) but the results are well worth the effort. These simply are the best S54 head studs we've found for the E46 M3 6 cylinder engines, and we highly recommend them in both the racing and forced induction arena. (Due to the additional clamping force between the head and block, these are IDEAL for turbo charging and supercharging!)

Converting from the factory BMW head bolts to head studs makes it much easier to assemble an engine, especially a racing powerplant which must be serviced frequently (and quickly!), and also ensures proper alignment of the head and gasket. Head studs also provide more accurate and consistent torque loading. Here's why: When you use bolts to secure the head, the fastener is actually being "twisted" while it's being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A head stud should be installed in a "relaxed" mode -- never crank it in tightly using a jammed nut. If everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. An information sheet is provided with each set. Kit includes everything pictured -- 14 head bolts, washers, bolts and assembly lubricant.

These head studs fit the following BMWs/engines
2001-2006 E46 M3 coupe & convertible
2001-2002 MZ3 M Roadster & M Coupe (with S54 engine)

Genuine BMW Exhaust Camshaft Position Sensor - E46 M3 E39 M5, MZ3, MZ4, Z8 (more info)

Sensor for: Exhaust. One weak point on BMW engines for years has been the cam position reference sensor. On the S54 engine in the E46 M3, M Roadster, and Z4M, there is one sensor for each cam. The sensor tells the computer the position of the cam on cylinder #1. The computer relies on the sensor's information to set injection timing and VANOS control. When a sensor goes bad, the computer loses track of what position the cam is in. While the engine will continue to run (taking its measurements from the crank position sensor), the entire system is thrown off. The engine may stumble or run rough, but not misfire, and there will be a loss of performance.

Each cam sensor also doubles as a sensor for the VANOS. So when the sensor goes bad, the VANOS will revert to a safe mode and will not advance.

While the engine will still run with a faulty cam position sensor, it's not running in its finest tune. The DME will have fault codes related to the cam sensor or for the VANOS. This is the Original BMW sensor with a new o-ring.

Oil Pressure Switch (fits most BMWs) (more info)

Having your oil pressure light come on can mean very serious problems. Or it could just be this switch that fails several times over a car's lifespan. By no means should you ignore the warning light but replacing this sensor could be the actual culprit. The other problem with this switch is that oil can leak past its seal. With the oil under a lot of pressure at this point, the oil loss can be a serious concern. It's a simple replacement when doing most oil change work.

Constant Pressure Valve for E46 M3, MZ3 (S54), and Z4 M (more info)

Oil leak on the E46 M3? The constant pressure valve, or oil pressure relief valve, is the most likely reason. This screw valve, located on the exhaust side of the engine block, has a steel o-ring that becomes flat over time, allowing oil to leak around it and down the back of your engine, transmission, undertray, and eventually to your driveway. If you see an oil leak around your transmission and think it's the rear main seal or from the oil pan, try replacing this first. Replacement is the only remedy as the washer on the screw has deformed in shape. The constant pressure valve helps to keep oil up in the cylinder head so you want a direct replacement part - not an aftermarket 'solution'. This is an Original BMW part. One required.

Applications:
1993-1999 Euro E36 M3 (S50 Euro, S52 Euro engine)

Idle Control Valve - M50, M52, M52TU, M54 (more info)

Rough or hunting idle? Stalling? Sputtering? These are all symptoms of poor fuel delivery or a vacuum leak in your intake system. The idle control valve is one of the areas that you can check to fix these issues. The ICV is basically a electrically-driven throttle body that regulates the air/fuel mixture at light throttle openings. Over time, the ICV can become gummed up with oil and carbon, resulting in slow or blocked operation. Worst case, the electric motor inside will freeze which will stall the engine.

The ICV will typically need to be cleaned or replaced every 100k miles. It can be cleaned with carb cleaner but for seriously dirty or old ICVs you may want to replace the whole unit with a new one. There is also a hard rubber seal between the ICV and the manifold and this should be replaced as well. You may also want to replace the Crankcase Vent Valve as it can also fill up with oil and carbon and replacement can be done at the same time as the ICV.

Add a new ICV to your M50 Manifold Upgrade to save time and money!

N51/N52/N52N Intake & Exhaust Camshaft Sensor Triggers for Bosch Motorsport Management Systems (more info)

The “Quick-Start” feature recently implemented by Bosch in their Motorsport ECUs is a more economical feature since the engine can now start from anywhere in the firing order. Conventional previous systems would require a full 360° rotation for the ECU to synchronize the firing order before allowing the engine to start. The Bosch Motorsport system is much more efficient as it does not waste battery power or add undue wear to the starter and alternator. The faster start is also much safer for critical engine components as there is less cranking with low oil pressure. These Cam Position Sensor Triggers were developed for our own Grand-Am team, saving you the cost and time to design and manufacture your own. We have developed these specifically for the Bosch Motorsport engine management but they may also work on other aftermarket engine management systems.

Advantages of TMS Quick-Start cam trigger wheels –

Precise CNC manufacturing (not stamped steel)

Less mechanical wear on engine components while cranking with low oil pressure

Less mechanical wear on starter from repeated cranking

Less draw on battery

Less wear on alternator over time.

Improved fuel economy as less gas is used during the cranking process.

ARP Connecting Rod Bolt Kit - E36 M3 S50/S52 (US only), E46 323/325 and more (see list) (more info)

Set of 12 ProSeries connecting rod bolts, made by ARP -- the world leader in fastener technology. Each bolt is made of ARP2000 material, which exceeds the strength of 8740 Chrome Moly, and is able to achieve clamp load at 220,000psi. ARP2000 fasteners are used widely in motorsport and drag racing as an upgrade from 8740 Chrome Moly in both steel and aluminum rods. These are simply the best connecting rod bolts available, making them ideal for ultra high performance, racing and forced induction applications.

This set replaces the factory BMW rod bolt number 11-24-1-739-728 (11241739728) which measures 44mm in length. The 44mm BMW rod bolt was used on all US spec E36 M3 (3.0 and 3.2 liter), 1999-2000 E46 323i/323Ci, 2001-2005 325i/325Ci, Z3 1.9,2.5 and 3.2, as well as Z4 2.5. It was also used on SOME of the M50 2.5 liter engines from 1992-1995 -- but check before ordering! Opened ARP bolt kits are not returnable. If your M50 2.5 liter engine has 53mm rod bolts, you will require kit part# 201-6301 instead.

These ARP connecting rod bolts fit the following BMWs:
1992-1995 E36 325i/is *** with 44mm rod bolts only ***
1995-1995 E36 M3 S50 3.0 liter (US model)

This ARP main stud set is for the S54 3.2 liter, as found in all 2001 to 2006 E46 M3, as well as the 2006-2008 Z4 M Roadster and M Coupe models. Switching to the ARP main stud kit eliminates main cap walk and fretting, as well as protects the threads in your engine block. Each stud is made using the best materials, process, design and engineering, which exceeds even the most stringent racing and aerospace specifications. This S54 main stud kit includes hardened parallel-ground washers and aerospace quality nuts.

The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 190,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others. On the E30 M3, there's no reason to settle for anything less than the best, which is why we carry and use ARP fasteners and studs on our own BMW race cars.

This ARP main stud kit fits the following BMWs:
2001-2006 E46 M3 3.2 liter coupe/convertible
2001-2002 MZ3 M Coupe & M Roadster (S54 engine)

Coolant/Washer Level Sensor (installs in expansion tank) - Many BMW (see list) (more info)

This is the sensor / sending unit that notifies the computer if your coolant level is low. When this fails, it can give a false indication of low coolant -- or worse, not inform you of a low coolant situation which could potential cause overheating. (Note: This sensor is also found in the windshield washer container, to alert the computer when you are low on washer fluid)

This sensor also serves as the washer fluid level sensor on many models.

This fluid level sensor is found on the following BMWs:

Thermostat With O-Rings - E46 M3 (more info)

Replacement stock thermostat for E46 M3, Z3M w S54 engine, Z4M. The thermostat can be replaced on the E46 M3 without removing the water pump. This can save you money if the pump still has life left on it but the thermostat needs to be done now. Symptoms of a bad thermostat include an erratic temp gauge and a fault code. When replacing the thermostat, there are three o-rings that will likely need to be replaced – between the thermostat and the water pump housing, and two on the coolant tube going to the head. We also recommend new hoses, clamps, and BMW coolant. Replacement should take about one hour.

Note: even though this can be done without replacing the water pump, the job involves removing the same items to access this area. And opening the thermostat housing will spill a lot of coolant. In other words, if you don't replace the water pump at the same time, you're going to repeat this process all over again when the pump needs replacing. We offer a complete overhaul package that covers everything you need if you want to it all at once.

This item fits the following BMWs:
2000-2001 E46 3 Series M3 M3 Convertible 2000-2006

Underdrive Power Pulleys

Turner Motorsport Power Pulley Upgrade Kit - Z4 2.5/3.0 (more info)

Underdrive Power Pulley Kit for Z4 2.5/3.0 2003-2005

As used on our racecars and street cars, these are engineered not only to be the best pulley kits on the market but also to provide the best compromise between performance and reliability. Specifically, we have designed them to underdrive the water pump, and the alternator*. The Z4 has electric power steering and therefore does not need a third pulley. Adding these is like getting FREE HORSEPOWER - there are no downsides and underdriving each of these accessories has been proven safe through years of on and off-track use. We do not believe it is safe to change the crankshaft pulley due to the potential harm to the crankshaft. These kits provide a 10%-20% overall reduction in driving your car's systems and have been dyno-tested with a gain of up to 11hp.

Kit includes water pump, alternator pulleys, and belt. The Z4 has electric power steering and therefore does not need a third pulley. The T-6061 hard anodized aluminum pulleys account for a 10 to 20-percent decrease in accessory speeds, reducing the load on the engine but still maintaining a safe margin for reliability on all components. Installation involves removing the fan for easy access to the front of the engine. The main drive belt comes off easy and each pulley is mounted with Allen head bolts. Typical installation time is 1.5 hours. New main drive belt is included. The pulleys were good for 10.7hp at 6960 rpm and 8.1 lb-ft of torque at 5550 on the 1995 M3.

VANOS-Related Parts

VANOS Filter for S54 Engine - E46 M3, MZ3, Z4 M (more info)

The S54 engine uses BMW's VANOS variable-valve timing mechanism. There is a filter inside the oil pressure valve that prevents contaminents from lodging in the system. Replacing or cleaning the filter is simple insurance to prevent VANOS failure. And a clean filter allows oil to pass unobstructed, meaning more efficient VANOS operation. This tiny filter slips on the end of the oil pressure valve, located on the side of the VANOS unit. Replacement is a simple procedure with new o-rings included.

Applications:
2001-2002 Z3 M Coupe, M Roadster with S54 engine
2001-2006 E46 M3 coupe, convertible
2006-2009 Z4 M Coupe, M Roadster

Vanos Unit with Solenoid - Rebuilt - S54 - E46 M3, Z3M, Z4M (more info)

The E46 M3, the Z3 M Coupe/Roadster and the E85/86 MZ4 Coupe/Roadster all came equipped with the S54 engine which was a much more complex engine than the earlier US Spec M3 had. The vanos on the S54 also evolved into a more complex unit and has it's own set of inherent problems that many S54 owners will run into eventually. The S54 Vanos controls both the intake and exhaust camshafts to improve performance, torque, idle characteristics and emissions. A high pressure (1200psi) control system is used to ensure responsive and accurate camshaft adjustments required by the high performance M engine. The back of the vanos houses a radial oil pump to produce the 1200psi of oil pressure. This pump is mechanically driven by a hub on the exhaust camshaft, which is one of the common failure points on this engine. The vanos also uses 4 solenoids which are attahed to the bottom of the unit in a non-rebuildable aluminum case. These solenoids are very sensitive to oil pressure and can easily become clogged or damaged over time due to contaminates in the oil. We highly recommend changing the oil every 5000 miles and only using the BMW 10w60 High Performance oil to prolong the life of the vanos. Typically the S54 vanos does not exhibit the common diesel rattle under normal operation. If you notice that your engine has suddenly become noisy we recommomend that the car not be driven any more than necessary until the source of the noise can be determined. This S54 vanos comes fully rebuilt with brand new solenoids and solenoid valves. This is the exact same package the dealers sells, but at half the cost.

Water Pump - M50, M52, M52TU, and M54 Engines with Metal Impeller (more info)

The early M50/M52 engines had a serious weak point: the water pump. BMW originally used a plastic impeller in the waterpump. This would degrade over time and eventually break apart. Your car overheats immediately. This water pump is an updated one with a metal impeller. BMW has since released a water pump with a composte impeller that does not have the same issues and is just as reliable as the metal impeller version. But for piece of mind, the metal impeller is tough to beat.

This waterpump fits the following BMWs:
1999-2006 E46 BMW 323i, 323Ci, 328i, 328Ci, 325i, 325Ci, 325xi, 330i, 330Ci, 330xi

Water Pump - M52tu, M54 (Original BMW) (more info)

This Original BMW water pump is the latest updated design with a composite impeller. The composite material (similar to Kevlar) is much stronger than the problematic plastic impeller from past water pumps. And it's lighter than the aftermarket metal impellers so that means less strain on the bearing. For an OE/OEM replacement, we have found that this is the highest quality and longest lasting waterpump available.

This waterpump fits the following BMWs:
1999-2006 E46 3 series - 323i, 323Ci, 328i, 328Ci, 325i, 325Ci, 330i, 330Ci

Water Pump Pulley - E46 E39 Z3 (more info)

This is the stock water pump pulley that mounts between the engine fan and the water pump. We have seen these plastic or composite pulleys crack around the mounting bolt holes. If left un-noticed the whole pulley can fall apart which will immediately disable the car and possibly leave you stranded. It can also break while performing other work around it such as removing the fan, replacing the water pump, or even just replacing the belt. Replacing this pulley while doing the water pump can be a good preventative measure.

This item fits the following BMWs:
