Audi A4 Air Filter - 1996-01

Extend your Audi engine life and reduce maintenance costs with regular engine air filter changes. The engine air filter is responsible for the removal of dirt, particles, dust, and soot before entering the engines air intake system. This prevents accelerated internal engine wear or damage and sensitive electronic component damage.

We recommend replacing your Audi air filter once a year or every 30,000-40,000 miles, which ever occurs first. Vehicles that drive consistently down dirt or gravel roads should have the engine air filter replaced more frequently, such as 30,000 miles. Those spending more time on clean roads can change there engine air filter less frequently, such as 40,000.

Also something to consider is forced induction engines ingest a higher volume of air into the intake system when compared to a non-forced induction engine. This gives more opportunity to dirty or clog the engines air filter. Forced induction engines with turbochargers or superchargers should have the air filter changed more frequently such as every 30,000 miles.
