Find Parts That Fit Your Vehicle

BMW Electrical Sensors, Switches, & Relays

Electrical gremlins can be very frustrating. Luckily your BMW's electrical system is better than most, even if it's 25 years old. Here you will find electrical relays, sensors, switches, and modules for the engine, camshaft, and crankshaft. Our parts are OEM, Genuine BMW, or approved aftermarket brands that we have an excellent track record with. There is no middle ground with electrical parts - it either works perfectly or not. And there's nothing more frustrating than a new part that fails right out of the box. So it's important to choose quality replacement parts over a cheap but faulty piece.

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.

In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. The AAF E46 Jump Post Relocation Bracket makes it easy to adjust camber/caster on your race car by getting the factory jump post out of the way! In race car applications, the desired camber and caster settings can cause the strut tops and shock adjusters to interfere with the factory jump post. This kit takes just a few minutes to install and makes using strut braces and adjusting camber plates just that much safer and faster.
