Bosch BMW Electrical Sensors, Switches, & Relays for BMW I12 i8 B38 1.5L

Clear BMW chassis

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.

The mass air flow sensor measures the amount of air flow to tell the computer how much fuel to add to the mixture. If the MAF sensor malfunctions, there could be too much or too little fuel added to the mixture.
