You are hereby appointed as the official cheap product tester for Crossfireforum.org. So far rear diffusers which you purchased inspite of many posts here warning those from The Crossfire Store were total junk and then had to return them. NOW you're going for a cheap oil catch can you found on E-Bay.

I personally know that most forum members are passionate enough about their Crossfires to invest in Needswings products, ALL Needswings products have been researched / tested / quality built / and proven. Also Rob's excellent customer service is simply second to none!
You go ahead and try the cheapy stuff. Just sayin' . . .
