How about Nismo's CAI? I got my Z back in March and it's sitting bone stock at the moment. A CAI is one of the first things I plan to do. The worry of voiding my warranty is what gives me the push to consider Nismo's products first, and everyone else's stuff 2nd.
I guess what I'm really trying to find out is whether or not Nismo's products are decent, legit, and worth the $$$ they're asking......or just dealer-infused hype....???? Anybody with any advice/experience with these products???
