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.

Whether you're building a dedicated track weapon or upgrading your street machine for ultimate reliability, unsprung and upper-chassis weight is the enemy of performance. Positioned high up in the engine bay or rear corners, a heavy factory battery negatively impacts your car's center of gravity.
