|K&N FilterChargers® use a specially formulated oil to attract and suspend dirt to the cotton-gauze filtration surface. Over time, dirt accumulates on the filter and airflow can be reduced. This is where the K&N Recharger® Kit comes to the rescue. Included are a cleaning solution and dirt-attracting oil, both of which are formulated specifically for K&N's cotton-gauze filter media.|
Using the K&N cleaning kit is surprisingly easy and involves just seven simple steps: 1) Pre-cleaning with a soft brush to dislodge loose dirt, 2) Spraying on the cleaning solution and allowing it to soak in for 10 minutes, 3) Rinsing with low-pressure water from the clean side to the dirty side, 4) Shaking out excess water and allowing the filter to dry naturally, 5) Lightly oiling each filter pleat and allowing the oil to impregnate the gauze, 6) Allow to set for 20 minutes, 7) Checking and re-oiling the light spots and finally reinstalling the filter. Typical filter-service interval is about 30,000 to 50,000 miles, depending on conditions (more often in dusty or off-road environments).
Two K&N Filter Care Service Kits are offered. Both include a 12-ounce bottle of Cleaning solution, but Oil packaging varies. Choose from the 8-ounce Squeeze Oil version (Part #99-5050) or 6.5-ounce aerosol Spray Oil (Part #99-5000).
