STEP 2 – Rinse Your K&N Air Filter

Rinse off your air filter with cool low-pressure water applied to the clean side out in order to flush the dirt out of the filter.  Continue to rinse the filter until all traces of cleaner are gone.  It may be necessary to repeat steps 1 and 2.

STEP 3 – Dry Your K&N Air Filter

After rinsing your filter, gently shake off the excess water and only allow filter to dry naturally.  Do not apply oil until the air filter is completely dry.

STEP 4 – Apply K&N Air Filter Oil

Apply K&N air filter oil evenly along the crown of each pleat.  Allow the oil to wick for approximately 20 minutes then touch up any light areas on either side of filter until there is a uniform red color at all areas.
