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 FILTER OIL

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. K&N offers 1/2 ounce pillow pack air filter oil for the smaller jobs and one gallon jug air filter oil for bigger jobs.
