These fuel injectors, Bosch part# 0 280 155 968, are very popular in many forced induction setups, as they flow enough fuel to prevent detonation at high rpm, and maintain adequate fueling. To use these on a BMW, you must have specialized tuning, as these provide far too much fuel with a stock or naturally aspirated setup. These injectors are often referred to as the "green top" or "green giant" injectors, which are also used in Ford Mustang Cobra applications. This newer generation fuel injector replaces the older style (and now discontinued) EV1 fuel injectors, often referred to as the Ford Racing EV1 fuel injector or M-9593-F302 ). They are rated at 42# / 42 pounds @ 2.7 BAR. In a BMW, which has a 3.5 BAR system, they provide approximately 47 PSI. These are sold individually, so be sure to order enough for your needs.

This is the OEM Bosch ignition coil that is the current replacement for most BMW 6 and 8-cylinder engines built since 2003. It's listed as a replacement coil for M54, M56, S54, N52, N54, N62, N63, N73, S63, S63TU and other engines. BMW has made numerous changes to ignition coil part numbers in recent years but has approved this part number to work in the vehicles listed in our fitments tab. This part number replaces previous BMW part numbers 12130390064, 12130148594, 12131712219, and 12137551260.

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code but not always a check engine light. A misfire code may be related to an ignition coil but could be from other things as well. Sometimes a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.

This Bosch part also satisfies BMW's service bulletin for 2001-2003 E46 M3 ignition coils (SIB 12 24 05). That SIB calls for Bremi or ERA brand coils but BMW has replaced them with this Bosch design.

Bosch is one of the largest OEM producers of Genuine BMW and aftermarket parts in the world, providing parts for almost every major automotive manufacturer. Bosch has likely supplied many of the original electrical (and mechanical) parts for your BMW. Thanks to their quality, high durability, and reliability, you should expect a long service life from Bosch products.

As a leading source of high performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts.  All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

Sold per coil. Includes connecting boot.

This is an OEM INA 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 belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-M54 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. If you have a mechanical belt tensioner, the pulley can only be replaced with a new tensioner.

OEM Schaeffler (INA, LuK, & FAG) is an engineering company that focuses on high-performance, precision manufacturing. With their individual brands INA, Luk, and FAG providing exceptionally high quality parts directly to BMW, as well as countless other automotive companies, their history of reliability and variety of offered parts makes Schaeffler a go-to replacement parts provider for all of us here at Turner Motorsport.

If you have ever attempted to do a valve job or cylinder head gasket project on an M42, M44, M50, or M52 engine you know that the repair manual will refer to the special BMW timing tool kit. This tool kit includes a flywheel locating lock pin, and a special set of camshaft locators that lock the cams in a precise location. The tools are very easy to install. The kit is specifically designed to hold the engine and cams in proper timing during the cylinder head removal and re installation process. This avoids the chance of bending the valves doing the head install process. The precision ground holding blocks lock over the square ends of both intake and exhaust cams. The CNC machined flywheel locating pin passes through a hole in the rear of the engine block and passed through a machined hole in the flywheel.

To avoid improper cam timing on the latest BMW engines, the factory has devised a cam timing system that locks the crankshaft and cams into a specific position prior to cylinder head removal. This method was devised to avoid any misalignment, resulting in piston to valve damage. Unfortunately without these tools re-timing the camshafts after a valve job is almost impossible. The factory specification manual does not supply installation specifications. This cam timing kit includes all the necessary components to do the job.

This item fits the following BMWs:

NOTE: Not compatible with S50B30 and S50B32 Euro engines!If you have ever attempted to do a valve job or cylinder head gasket project on an M42, M44, M50, or M52 engine you know that the repair manual will refer to the special BMW timing tool kit. This tool kit includes a flywheel locating lock pin, and a special set of camshaft locators that lock the cams in a precise location. The tools are very easy to install. The kit is specifically designed to hold the engine and cams in proper timing during the cylinder head removal and re installation process. This avoids the chance of bending the valves doing the head install process. The precision ground holding blocks lock over the square ends of both intake and exhaust cams. The CNC machined flywheel locating pin passes through a hole in the rear of the engine block and passed through a machined hole in the flywheel.

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem. 

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking.

Every 60-80,000 miles, we recommend replacing your spark plugs to ensure your ignition system is running optimally. Over time carbon can build up around the head of the spark plug and decrease spark strength and effectiveness, leading to weaker fuel mixture detonation, misfires, and potential check engine lights. To prevent this, have put together our High-Performance Ignition Service Kits. These kits include new Bav Auto High-Performance Ignition Coils, new spark plugs, dielectric grease, and a BMW spark plug service label to keep track of when your spark plugs were replaced.

Bav Auto's Ignition coils feature core windings that have been modified to increase firepower and promote a faster, more efficient burn. This gives your BMW/MINI increased torque in the lower range of RPM and more horsepower in the upper range. Exact improvements depend on the current condition of your engine, but you'll definitely feel the difference. They'll also improve your fuel economy.

From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over.

Replacing the rod bearings requires mechanical knowledge and skill, a clean workspace, and several specialist tools. Our preferred procedure is to leave the engine in the car but remove the front subframe. The engine must be supported from above with an engine brace. Removing the front subframe involves disconnecting the control arms and steering rack and steering column. The oil pan can then be removed and you can access the connecting rods and bearings. Replacing the rod bearings themselves is straightforward but patience and forethought will be extremely helpful. In addition to analyzing the severity of the rod bearing wear, the crankshaft must also be inspected closely for damage. Rod bearings that have been severely worn may have damaged the crankshaft (requiring replacement or machining).

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code but not always a check engine light. A misfire code may be related to an ignition coil but could be from other things as well. Sometimes a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code but not always a check engine light. A misfire code may be related to an ignition coil but could be from other things as well. Sometimes a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.

Piston Ring Filer

The Schwaben Piston Ring Filer is a vital tool for obtaining the precise end gap necessary for optimal piston ring performance.

This filer allows you to swiftly and accurately file piston rings to exact measurements, enhancing your engine’s efficiency and lifespan. By simply positioning the piston ring and turning the handle, you can easily rotate the abrasive wheel for a smooth and effective filing process.

**Note:** For the Schwaben Universal Piston Ring Compressor, check out T25805755!


Key Features:

  • Optimize Performance: Achieve the perfect end gap crucial for top engine efficiency.
  • Quick and Precise: File rings to exact specifications with ease.
  • Easy Operation: Position the piston ring and turn the handle to effortlessly rotate the abrasive wheel.
  • Enhanced Engine Longevity: Accurate end gaps contribute to longer engine life and better performance.


Instructions:

1. Position the Ring: Place the piston ring on the outer edge against the stop and align the ends squarely against the grinding wheel. Apply light, even pressure against the wheel to prevent grinding too large a gap.
2. Operate the Tool: Turn the handle so the grinding wheel turns towards the inside edge of the ring (counter-clockwise when viewed from the handle side of the tool).
3. Exercise Caution: This is a diamond grinding wheel. It cuts fast!

Checking Piston Ring Gap:

1. Deburr the Ring Ends: Carefully remove any burrs on the ring ends before placing the ring in the bore. A light touch with a fine abrasive stone works well.
2. Clean the Rings: Thoroughly clean the rings with lacquer thinner or acetone, as the paint coating from the factory may occasionally scratch the cylinder bore. Always wear gloves during this process.
3. Position the Ring in the Cylinder: Place the ring squarely in the cylinder bore, about 1" down from the deck surface. An upside-down flat-top piston will help you properly square the ring.
4. Measure the End Gap: Use a feeler gauge to measure the ring's end gap. Apply light grinding pressure and check frequently to avoid making the end gap too large.
