[QUOTE="gn83tm, post: 824695, member: 38076"] Soap; I use the Uni filters also but always clean both elements. The outer element is quite coarse so most of the fine particles of dirt probably end up in the finer, inner filter. The outside usually has a lot of larger particles and weed seeds. The flow bench comparison tests I have show a Unifilter flowing 4.5 cfm/sq in, a paper filter flowing 5.2 cfm/sq in, and a K&N flowing 6.5 cfm/sq in. Looks to me like you could run a lot smaller K&N or paper filter and still get the airflow you need. The same test showed a K&N after the Baja 500 flowing 5.1 cfm/sq in. It was covered with up to 1/4" of dirt over its entire surface. The tests I am referencing are from a book titled "Performance With Economy" by David Vizard. sloopy; I use the nasty, sticky, hard to get off your hands, filter oil from Bel-Ray. [/QUOTE]
