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.

These WPC-treated bearings are the best we have seen! WPC is a shot-peening treatment at a microscopic level. It's perfect for sensitive surfaces like bearings. The WPC treatment removes imperfections and high spots, while creating a surface that retains oil better than the original surface. This greatly reduces friction. The bearings in this kit are original equipment KS bearings that are sent to WPC for treatment. The treated bearings are stronger with less metal fatigue and less friction than buying off-the-shelf bearings from the dealer.

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.

What's better than using new crank bearings in your next engine build? WPC-treated bearings! What is WPC, you ask? WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. What are you waiting for? Use WPC-treated bearings on your next engine build or crank service!

Upgrade Your BMW with ECS Baffled Oil Catch Can

Modern emission regulations require a closed PCV/Breather system for cleaner operation. However, inefficient oil particle capture can lead to excessive oil vapor ingestion, causing carbon buildup, reduced performance, and fuel economy. ECS Tuning's updated ECS Baffled Oil Catch Can, now with an easy-to-empty 1/4" drain fitting, is engineered to collect toxic blow-by gases, minimize carbon deposits, and reduce oil contamination within engine oil. Recirculating oil vapor ensures emissions compliance without venting to the atmosphere.

  • Key Features:
  • Highly Efficient Oil Separator: Strategically positioned 4 chamber baffle system maximizes oil/air separation and minimizes oil droplets in the intake tract.
  • Integrated Dipstick: Knurled and black anodized oil dipstick simplifies oil volume inspection.
  • Reservoir: Available in 6oz or 8oz capacity with a 1/4" NPT drain plug fitting.
  • Serviceable: Easily removable baffle plates and drain plug for cleaning.
  • Easy/Customizable Installation: Combine with the ECS Universal Bracket Kit for simplified installation and adjustable mounting locations.
  • Leak-Free Fittings: Machined -10AN ORB (O-Ring Boss) fittings available for secure connections (fittings sold separately).

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. AAF's Oil Pressure Sensor Relocation Kit allows for an aftermarket low pressure switch as well as oil pressure sensor, or two 1/8' NPT pressure sensors to be installed. This can allow a gauge or light to be on the dash and still log oil pressure in a data logger. This kit also moves the oil pressure sensor away from the engine and onto the chassis (or any other spot) where is it much easier to access, or install larger size diameter sensors. Fits all M20 Engines. Features: 4AN Stainless Steel Braided Line Banjo Bolt and Fitting (installs onto block) 3 Way 1/8' NPT Tee Fitting, for hose from block and 2 sensors. Note: This kit does not come with sensors – the factory low pressure switch can NOT be used. An aftermarket 1/8″ NPT low pressure switch can be used with the factory wire.
