Air filter oil K&N 0.4lt

K&N cotton cloth air filter oil: specifically formulated to work in conjunction with the cotton cloth from which K&N air filters are made to achieve a superior air filtration system. Penetrates quickly into the folds of the filter and remains suspended there, increasing filtering power: do not use gasoline, kerosene, thinners or blow the filter with compressed air. Use only K&N filter oil, regular oil damages the cotton fabric and does not allow enough air to pass through the fabric.
