For oiled filters: The cleaning interval will depend on your driving conditions. We recommend that you inspect your filter every oil change or 6,000 miles. If debris has built up on your filter equal to the height of the wire mesh, your filter should be cleaned and oiled. Servicing your filter more frequently will result in better performance. At a minimum, the air filter should be properly serviced using a Precision Cleaning & Oiling Kit every 12,000 miles.
For dry filters: The cleaning interval also depends on your driving conditions. We recommend that you inspect the filter 5,000 miles. Blowing out your dry filter with compressed air will extend the life of the filter. Depending on the conditions we recommend replacing the dry filter every 15-30,000 miles.
Using compressed air, blow off the outside of the dry filter keeping the air nozzle moving and no closer than 6 inches to the media. This can be done while the filter is still in the vehicle. If you would like to blow it out further, remove the filter and blow it out from the inside out being careful not to concentrate the compressed air in one location in the media.
Regardless of which style of filter you utilize, we recommend that you use a filter wrap as this will keep the bugs and other big stuff out of the filter media which will extend the life of your filter and make it easier to service.
