Bosch 12109 Oxygen Sensor
This part comes in original Bosch packaging.
Properly functioning oxygen sensors are important when it comes to your vehicle's fuel efficiency and reducing harmful exhaust emissions. That's why checking for, and possibly replacing, a worn-out oxygen sensor is an important part of every routine vehicle tune-up. And a routine vehicle tune-up is more than just routine when you use Bosch Oxygen Sensors along with Bosch Spark Plugs as part of a Bosch Premium Tune-Up. You'll be helping the environment and your vehicle's fuel efficiency over the life of the oxygen sensor.
