K&N Maintenance of washable air filter Air filter cleaner

K&N Air Filter Cleaner is the only cleaning agent suitable for cleaning K&N air filters.

Using any other cleaning agent will void the warranty on the air filter and will almost certainly damage the cotton filter material.

K&N Power Kleen Cleaner dissolves built up dirt and old filter oil and can be rinsed away with water.

It is so good at cleaning greasy dirt and soot that it is also used as a very strong degreaser. Full instructions on the bottle.

CAUTION: Do not use on polished or anodized aluminum.
