Audi Oxygen Sensors

Properly functioning Audi 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 Quality Oxygen Sensors along with
Bosch Spark Plugs as part of a Premium Tune-Up. You'll be helping the
environment and your vehicle's fuel efficiency over the life of the oxygen sensor.
Save up to 10% a year in gasoline cost.
