One gallon of premium quality filter oil for a great price. Need I say more?

5.0 Less expensive

Being retired I have more time to enjoy off roading, and exploring the deserts, mountains, and scouting rather than the 9~5, M~F. I purchased the K&N filters, engine and cabin years ago, two of each. The spares get installed when I reach pavement. I clean my filters with soap, then add the K&N filter oil with a small paint sprayer attached to my air compressor. Much less money to keep a clean set, and less to worry about. Our HandiVan also has K&N engine intake filter.

5.0 Great value

K&N filters are the best, I have added these to all my cars and motorcycles since I first found out about them sometime around 1997. The easiest difference to notice is the throttle response, especially in large engines. The oli is a must, and found this larger size to have surprisingly good value.
