Never use a K&N air filter without oil. (The filter will not stop the dirt without the
oil.) Use only K&N formulated air filter oil.
K&N air filter oil is a compound of mineral and animal oil blended with special
polymers to form a very efficient tack barrier. Red dye is added to show just where you
have applied the oil. Eventually the red color will fade but the oil will remain and will
filter the air.
