Installation Notes and Tips

Verify the thread size, height, and outer diameter before installation. Replace the filter at the manufacturer-recommended oil service interval, and confirm the vehicle uses the correct oil specification for the engine. For Audi A6, Audi A6 Quattro, and Audi S6 applications, match the filter to the OE service schedule and inspect the sealing surface during every oil change.
