| Painter, don’t throw that air filter away. The K&N filter will be good for several years if maintained right.
K&N makes an solution/cleaner ( you can also use any good detergent soap), you just spray on, let it soak for ten minutes, reverse flush out with water, let it completely dry, re-spray with K&N air filter oil.
That’s one of the reasons the K&N filters are so great… |
