Don't service your air filter on a time, mileage, or "looks dirty" basis!

Air filter service life depends on operating conditions. An air filter may restrict in a few hours/miles, or last several hundred hours (sometimes 100,000 miles or more). Monitoring the air filter with a Filter Minder® service indicator takes the guesswork out of air filter maintenance.
