Does Intake Manifold add Horespower?

[ChristianZ]

I have a 2004 350z Roadster with Nismo Cold Air Intake, headers, and dual catback exhaust. Is the intake manifold another good thing for me to add and if so what are the results.

They say if you get a aftermarket one it flows better, but you usually can't use the factory FSTB. I say just get a intake spacer.

there are a few options on the intake, and it'll yield about as much as each of your other mods, I think the full boat of bolt ons yields something like 20 whp, makes a SC look like a great deal

Thank You for replying, you are not the first person to say and just get the spacer. What about a Pop Charger?

pop chargers are cool but look into the cosworth intake plenum its like 1100 bucks but herd it was put to all kinds of test so really its probley the best youll get for the money. id really like to get it myself when i find a way to get hella money in short time... but if you get it post your results cuz im curious
