BMW Electrical Sensors, Switches, & Relays for BMW 3 Series E93 (2007-2013)

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.

If your battery cables have become worn or frayed, or the IBS sensor has gone bad, its time for a replacement. BMW use the IBS, or Intelligent Battery Sensor, to determine not only the state of charge but also the batteries health and life expectancy. Using this data the car's charging system can appropriately supply the battery with the correct voltage, no matter the age.

Comes as a single cable with terminal and IBS Sensor pre-installed.
