NEW! Genuine BOSCH oxygen sensors!

Oxygen sensors, also called O2 sensors or Lambda sensors, are a critical component of your vehicle's engine management system. The oxygen sensor works by measuring the level of oxygen in the exhaust and providing that data to the engine control computer. The engine control computer correlates data from a variety of sensors and then calculates the optimal fuel mixture, ignition timing and other engine variables.
