Installation Notes and Tips

Replace the air filter according to the vehicle maintenance schedule or sooner if driving conditions are severe. Before installation, confirm the airbox shape and dimensions against the existing filter and verify the vehicle application by year, make, and model. For best results, inspect the airbox for debris and ensure the filter seats evenly in the housing before closing the cover.
