K&N 32 fl.oz. Air Filter Cleaner

K&N Air Filter Cleaner is the only cleaner formulated to clean K&N Filtercharger elements. The use of any other cleaning solution can void the filter's warranty, and quite possibly could damage the cotton materials. It works to dissolve the dirt build up and filter oil, and can be washed away with water. It is biodegradable and safe on paint, chrome, cast aluminum, plastic, rubber and vinyl when used as directed. Complete instruction on bottle. 32 oz. Note: Do not use on polished or anodized aluminum.
