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!

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.

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.

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.

This direct fit Bosch oxygen sensor plugs directly into your factory connector. No cutting or splicing required. 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 It fits BMW E23 E24 E28 E30. Bosch # 13 049.

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.

This is an OEM MAHLE fuel filter that removes dirt and other particle contaminants from your fuel.

A clogged fuel filter makes it difficult for your engine to get all the fueling it needs. Filters commonly clog from a deteriorating gas tank, bad fuel, or other debris in the fuel system. A fresh fuel filter addresses many fuel related problems including surging, stalling, cold start issues, and poor performance under a variety of conditions.
