Let me know what you think, I've never seen them. Just tried their website and couldn't find any for pre-2009 though. The only reason I use the oiled filter is because I constantly have to clean my air filter. Went about 10 K on my paper filter and it isn't in that bad of shape but since I got the oiled filter I have to clean it every 3k. I'm not gonna complain about cleaning my intake filter more often since it is the only fine particle protection the engine has.
