K&N replacement performance air filter for Audi A4

Audi A4 High performance replacement air filter from K&N

All of the K&N air filters are washable and reusable and are designed to fit right into the standard OEM Audi A4 airbox. No modifications are required by the owner.
And yes, we�ve heard the stories of customers who ran their K&N filter for 100,000 miles without a cleaning, but we believe cleaning after 50,000 miles to be the most beneficial service without sacrificing air flow.

The K&N filters are designed to provide up to a 4% increase in horsepower and torque. The amount of performance gain varies from vehicle to vehicle based on the overall factory design. The greater the restriction created by the stock paper element, the greater the potential performance gain when you switch to a K&N filter.
