I had my K&N installed on a friday and I got a CEL on sunday. Tried to get it off with fuse pull or else. So I putted back the G5CR back, got a scanner and cleared the CEL. No problem since with the G5CR, so I'm keeping it.
As for Vararam it's a wait and see for me. Everyone went for Airaid V1 and there where problems and they had to put out a V2. So I will wait for results before thinking buying one. Will see what the G5CR will do in hot weather, maybe it's good since the air flowing into the engine bay does'nt have any restriction.
