When you made the decision to take a step up to a genuine K&N Air Filter, you made a great decision, because whether you just replaced the stock filter with an upgraded version, or you’ve got a whole intake upgrade kit from this company, you ended up with a filter that’s guaranteed for a million miles, so it’s still practically new. Depending on conditions, you can often run these filters for up to 100,000 miles before cleaning, because the oiled gauze is a whole different kind of setup than your old paper filter, and you’ve saved a bundle, when you think about how many times you would have had to replace your cheap paper part by now. The time has come, though, and you need a K&N Air Filter Recharge Kit, so that you can get this baby cleaned up, properly oiled, and back on the vehicle, so that you go right back to the virtually unobstructed airflow you had when you bought it. If you’re just taking the step up to a performance filter right now, you might as well get the K&N Air Filter Recharge Kit at the same time, so you have it when you need it.
