Just what you need for cleaning a K%26N air filter

This is a cleaner and oil for K%26N reusable air filters -- if you have these filters (which are for cleaning yearly, typically) you need to clean and oil them yearly using this cleaner and oil. These were a good buy at WalMart (cheaper than other places I found them) and worked well on my K%26N filter -- the cleaner loosened the dirt well and it washed out with water, and then (after the filter dries) the oil does its job getting the filter ready for reuse. No problems. The oil has a nice notch on the top to make it easier to apply it to the crowns of the vents, which is a nice touch.
