Why do I need to replace my Audi A4 air filter?
With regular use, the Audi A4 air filter may become blocked by debris, limiting clean airflow. This can slow acceleration, cut fuel efficiency and put stress on the engine.
Keeping the filter fresh means your Audi A4 performs smoothly, uses fuel more effectively and avoids unnecessary strain.
How often should I replace the air filter?
Most handbooks recommend replacing the filter every 15,000 to 30,000 miles, but it depends on how and where you drive. For the most accurate details, see your Audi A4's manual.
