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 OEM fuel filter is a must during any major service or tune-up. With a clogged or dirty filter, you are starving your engine of gasoline which can result in dangerous cutting out, rough running, or even a no-start situation. Bosch filters are premium grade filters that will keep your fuel system in top shape the same as, or better than, Genuine filters, without having to spend the Genuine BMW price. We recommend changing the fuel filter as part of a regular 30,000 mile tune-up. But you may want to replace it more often if your regular fuel quality is low.  OEM replacement for BMW part number 13321270038, 13321268231, and 13329063165.

A new oxygen sensor can improve driveability and lengthen engine life. Ultimately, you achieve a smoother running engine that is more fuel efficient. Feedback from the oxygen sensor provides closed-loop control of the injected quantity of fuel for optimum air-fuel mixture, enabling virtually complete combustion to take place. Contaminants in gas and certain atmospheric conditions can drastically shorten the life of any oxygen sensor, therefore they should be checked with every periodic maintenance and changed if necessary.

This is the voltage regulator found on the back of the alternator. It's a normal wear item and the contacts are the first thing to check if you believe the alternator is not charging the battery (lights flickering or dim, battery light on in the dash, the engine quits without warning, or other electrical failures). The voltage regulator manages the voltage flowing through the car, especially to and from the battery. There are two carbon contacts on the regulator that control the magnetic field when the alternator is spinning and these contacts wear over time. A new set of contacts will be about 13mm in length. Anything less than 5mm and the voltage regulator should be replaced, regardless if that is the cause of your electrical problems or not. Most older mechanics will tell you to keep a spare regulator in your toolbox.

The carbon contacts can be replaced on their own but requires desoldering the old ones from the base and then soldering the new ones on. It may be easier to just replace the unit as a whole.

This is the OEM voltage regulator, made by Bosch or Hella. It's the one with the white base and fits most Bosch alternators from 1977-1995 (Valeo and other alternators look very different and have a black cover and base). This part number replaces the previous BMW part numbers - 12311271664, 12321279548, 12311722755, 12321711399 and Bosch part numbers 1197311021 and 1197311028.

For Alternator / Water Pump Belt

Hydraulic Belt Tensioner for E36, E46, E39 6-cyl models. This is the oil-filled tensioner that keeps the main drive belt in the proper tension. Over time the piston seals inside allow fluid to leak out. The tensioner becomes frozen or inoperable. Replacement is the best corrective action to take. This can be done during any belt or pulley service or anytime the fan is off the engine.

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.

Ignition coils are key to the efficiency and performance of your BMW. With a faulty ignition 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 the coil 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.

This item fits the following BMWs:

Your ABS sensors are the main tool that your ABS system uses when sending signals to the computer. If one of the sensors fail, a warning light will appear on your display alerting you of the situation and the system will no longer operate as normal. When a time comes when you are expecting the system to kick in, it will not, a dangerous situation if the driver is accustomed to it. Replace your worn out or broken sensors and make sure that everything is up to the task of snow, ice, and wet roads.

The oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance. Bosch's Oxygen sensors are high quality and will give you the longest and best performance for the price. 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.
