Product Details
Your engine relies on split-second data from both cylinder banks to perfectly balance the air-fuel ratio. If one pre-cat sensor is tired and slow, the other isn't far behind. Replacing your pre-cat oxygen sensors as a matching pair ensures symmetrical, accurate data readings across the entire engine block. Don't do the job twice—refresh them both at the same time to prevent uneven fueling and save yourself a second trip under the car.
Kit Features & Benefits:
Restore Power & MPG: Re-establishes precision, closed-loop fueling control for optimized combustion, razor-sharp throttle response, and maximum efficiency.
Kill the Check Engine Light: Clears common BMW fault codes related to slow O2 sensor response and aging heating elements.
Track-Ready, Direct-Fit: Engineered with factory-length wiring harnesses and OE-spec connectors for a seamless, plug-and-play installation.
No-Hassle Install: Comes with pre-applied anti-seize on the threads right out of the box to prevent future galling and make future service a breeze.
