Changes look really good. So front license plates aren't enforced in your area? I thought CA was strict about that.
Yes I did notice a difference it's more ridged and flat around corners. As far as the install and clearance. The install is fairly easy it takes about 1 1/2 hr. Clearance wise you have about a 1/4 inch above the blower. After market CAI, I think they say there is clearance problem with some not sure which ones but I'm sure you could call Steeda or e-mail them and they could provide you with that info. Cost wise I think it worth it.
