Its role in maintaining precise engine control makes it a must-have component for any serious E46 enthusiast. Upgrade today to experience the true driving character of the E46.
Oxygen sensors are used to monitor the oxygen content of the engine exhaust. That information is used by the engine control module to fine tune the amount of fuel supplied to the fuel injectors. In the BMW E46 6-cylinder engine, a pair of oxygen sensors is installed in the exhaust manifolds just ahead of the catalytic converters and another pair is in the pipes just after the converters.

When the O2 sensor can't register oxygen content before and after your catalytic converter, it doesn't know what to do with the fuel mixture and will default to run rich. Replace old failing oxygen sensors with OEM O2 sensors or quality aftermarket O2 sensors if you're looking to save a few bucks.
