Nice thanks. I think I will pick up one of those polished ones shortly. Super cheap. No performance gains I know so no need to spend $300+ for a hand rest.

 

As I have searched through numberous threads, and various arguements about intakes etc. I have concluded that the stock box is good not the loudest; which is where an aftermarket CAI comes in, I mean one cannot out due the engineers, maybe on a civic yeah. But to answer you question it should do a difference obviously not a feelable difference but I mean, but cutting the plastic piece one is allowing more air to easily get into the filter. The little plastic piece is there just in case water some how ends way the hell up there, that it wouldn't get "hydrolocked". The only feel able difference mod I have to say with 100% would be a single exhaust! . But one cannot go wrong with gutting the intake and installing a K&N filter. The stock one more than likely needs replacement anyways so why not go with a good brand
