Installation Notes and Tips

Replace the filter at the manufacturer-recommended service interval or sooner if driving conditions are severe. Confirm the air box is clean before installing the new filter, and verify the filter seats evenly in the housing to maintain a proper seal. Always match the part number and vehicle application before installation, especially when servicing a Subaru Crosstrek air filter or Suzuki SX4 air filter application.
