Audi A4 Oxygen Sensor

Audi is known for delivering powerful thrills, but your intricate mechanics require a very specific set of monitoring tools. When your o2 sensor fails, you feel a noticeable difference in the way your car performs – luckily AutoZone's aftermarket Audi A4 oxygen sensor restores that innate perfection.

Our A4 oxygen sensors are designed for your Audi computer's voltage requirements. They deliver data from your exhaust output, which tells your engine how much fuel to intake at any given time. The right fit is essential in order to properly adjust for changes in temperature, altitude and engine load. When you buy an o2 sensor for Audi A4, we eliminate the wait with Same Day Store Pickup (in most cases).
