    Comments about K&N Replacement Air Filter:

    Was fortunate to get one of these. Sold out everywhere else. Just did a simple drop into the air box. Immediately noticed a smoother ride between gear shifts. And appears to have a tiny bit more power or "oomph" while driving. Do not need to clean for another 50K miles, but will do it once a year.

                  Comments about K&N Replacement Air Filter:

                  Great filter, you can feel the intake change upon vehicle start up. Difficult install on 02 RSX due to tube which connects to Valve cover, requires some finesse to remove air intake box cover. Once box cover is off its a quick drop and go. Make sure your filter come with the "K&N INSTALLED" decal to put on top of the intake box.

                    I've never had a cleanable air filter. Do you just vacuum it out, hose it off, put it in the dishwasher? How do you clean it?

                      A:

                      The instructions you need to follow for cleaning this K&N Round Open Top Cotton Gauze Air Filter (Part No. E-2429) are: Tap the air filter on its base or side against a hard surface to loosen dirt and debris. Brush away the loosened dirt and debris with a soft-bristled brush such as an old toothbrush. Do this over a trash can or paper towels. Coat the filter element with K&N air filter cleaner. Either coat it completely with the spray and wait 10 minutes, or set it in a dish filled with the liquid cleaner and wait 10 minutes before removing it from the liquid and allowing it to sit for an additional 10 minutes. Flush the filter under a cold tap on a low pressure setting. Shake excess water from the filter. Set the filter on a clean paper towel. Let it air-dry at room temperature. Oil the filter with K&N filter oil when it is dry. Spray or squeeze the oil into the pleats of the filter. Let the filter sit for 10 minutes and re-oil any pleats that have not turned a reddish-brown color.
