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.

Race German has devoted themselves to providing quality products for late model BMWs that cover both street and track applications. Race German has now grown their catalog to a wide variety of models and products geared towards keeping your car looking and running nice. BMW's original C101 bracket which connects to the firewall and holds the diagnosis port unfortunately over time becomes heat soaked and brittle. The OEM bracket, which is no longer available, also features a flawed hinge design that easily wears and breaks. Race German has devised a solution to this issue and developed a new bracket! This heavy duty C101 firewall bracket is completely plug and play. These brackets are CAD designed and feature a two piece design with stainless steel hardware.

On the track or on the street, your BMW’s electrical architecture demands absolute consistency. A degraded positive battery cable introduces unwanted resistance, leading to weak starts, alternator strain, and erratic module behavior. When it’s time to replace a compromised factory cable, you don’t need over-hyped marketing—you need a part that fits precisely and restores factory grid integrity.
