Cleaning Icon


K&N® air filter cleaning supplies are available for both cotton and synthetic filters—removing filter-clogging build-up and helping restore your filter to exceptional performance. High-Flow Air Filters™ are composed of oiled cotton media, and should be cleaned with K&N® Power Kleen™ industrial strength degreaser before the re-application of filter oil. Synthetic filters should be cleaned with K&N synthetic air filter cleaner before being rinsed clean with water, and do not require filter oil.


K&N air filter cleaning kits include both filter cleaner and filter oil, which are designed to service any K&N oiled cotton air filter. Regular servicing can help restore airflow efficiency, allowing the filter to operate virtually as new.
