This is a Genuine BMW main relay for a variety of BMW models. The main relay powers vital systems in the car when the key is turned to the Start position. Things like the ECU and fuel pump require power from the main relay before they can work. The main relay is constantly powered so checking for power is easy with a test light. It should also make a 'click' sound when the ignition switch is turned. Note: relays look similar but can perform different functions, and electrical parts are non-returnable, so make sure you confirm this is the relay you need.
When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

This relay is used for the SMG system on the E46 M3 and various applications including secondary air systems on other BMW's. If you find that your SMG-equipped E46 M3 is not starting, this is one of the first places to check as it controls power to the hydraulic unit (the car will not start without hydraulics). Buy one to fix the issue and buy a second so you're not stranded in the future!

The engine crankcase in you car is filled with oil to keep everything lubricated, and to keep the oil inside of the engine, seals are used anywhere there is a seam in the engine, or any place a shaft protrudes from the engine. One such seal is the front main crankshaft seal. This seal is located around the the crankshaft at the front of the engine, and keeps oil from leaking out around the crankshaft. Unfortunately, over time seals will become brittle, crack and begin to leak due to their exposure to heat and oil.

The timing chain tensioner from the 1995 E36 M3 is a great upgrade for other Motorsport models - 1988-1991 E30 M3 and 1989-1995 E34 M5! This tensioner virtually eliminates the cold start-up engine rattle so common with the S14 and S38 engines. It makes the whole engine quieter and smoother. Any new tensioner will accomplish that but the S50 tensioner has several new features that make it superior to the original design. This unit also has a internally loaded spring, so installation is much easier than the old style tensioner (no need to squeeze the spring and hold it while installing). Includes oil seal ring (not pictured).

This item fits the following BMWs:
1985-1989 E24 BMW M635CSi M6 - M88/3, S38B35 engine

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.

Replacement engine oil filler cap with seal (Original BMW brand). Oil caps can go bad.... If the cap is not sealing to the valve cover it will result in a vacuum leak (poor idle, rough running, etc). It also helps regulate pressure in the cylinder head. While there is no life expectency, there's no downside to replacing it every few years. This is a Genuine BMW part.

If there is a large amount of oil on the sides of the engine or if you can smell burning oil, chances are it's a bad valve cover gasket. The gasket fails and allows oil to seep down onto the side of the engine and other parts causing a mess and reducing the amount of oil in your engine. This replacement gasket from Elring is perfect to prevent any further oil leaks.

Includes the following Seals:

  • Valve cover gasket
  • Spark plug seals

Elring is one of the biggest OEM names in the manufacturing of high quality gaskets that are available for very affordable prices. Elring has supplied many automotive names for years with the gaskets that seal your car's components from day 1 so you can rest assured that these components will last for a long time to come!
