I want to put a good cold air induction on my 94 z28. I just want to know which one will give me the best bang for the buck also I was wondering if a 52mm throttle body is worth 150 bucks?? Does it give any real power gains?

 

I would go with the Moroso CAI, I bought mine from Summit for $189.95, I've heard it gives pretty good gains. As for the Throttle Body, you really don't need a bigger one unless you are going to highly mod your engine, and if you go to big it could hurt your performance. But I think 52mm would be a good size if you wanted to upgrade, I don't think it would make much more power though.

 

Yeah i would just forget about the throttle body unless highly modified and i would say go morroso,dyno proven horsepower is what influenced me to get it,best induction kit for the money
