for a 2004 g35 looking to buy air intake, intake manifold/spacer, headers, high flow cats, exhaust. Preferably Carb legal stuff but is doesn't matter, i'm open to all ideas.

 

Skip the intake and keep the OEM airbox unless you just want it for looks. Get a 350Z tube and a 5/16th spacer or aftermarket upper plenum. Headers will give you performance gains but a pain in the a** to install. HFC's are a good way to go (Fast Intentions or Crawford) coupled with a cat back exhaust (Fast Intentions or HKS). Just my suggestions.

 

I put in an injen short ram induction system, a 5/16 spacer and they alone made quite a dfference. I want to put in a bigger guage Y pipe and eventually a full exhaust system. I think that it is better to go one step at a time to see what each alteration feels like instead of all out in one go.

 

thanks alot guys. just wondering what do you suggest on the spacer/ plenum there's alot out there

First one on the page there. Then a Z-tube/pop charger. Also headers aren't worth the trouble as it is a PITA x 100 to install them. I don't know about HFC, but get the megan v2 resonated test pipes. Exhaust? Thats up to which sound you like.

 

I agree. the motordne is a good part. If however the cost is something that affects your decision, blox make a part that is a lot cheaper and simpler to install and gives nearly as good a result.

 

if you plan on goin f/i in the future. then you should just skip the spacer for now and get a intake manifold. Pairing it with the sc to tc will give you more gains than a spacer.
