aftermarket Intake manifold

[Kunundrum]

What are the Pro and Cons of aftermarket intake manifolds.


I was looking at picking up one not sure what one yet.

I was thinking that I would loose my Fast Idle control valve with an aftermarket intake manifold since mine is OBD0 and most are for OBD-1

any insight on this

aftermarket ones claim better flow, usually have an off square main runner thus reducing resonation witch would mean better flow. As for the fast idel, cant help you there.

Pros - Better flow, bigger more straight runners.

Cons - Without cams or considerable mods, an IM isn't going to help much.

But, I think you're up to something quite tricky so an intake mainfold would be a good mod to do. Stock 1st gen B16 has a relativley tiny inake manifold, even compared to newer B16s. You will lose your fast idle control valve though. You don't drive that car in the winter anyway, do you?

Give consideration to find a used ITR intake manifold if thats something you could do. For the price they sell for you're not going to get better gains for the extra $$ spent on a new Skunk2 manifold. (hp for dollar)


Sidenote: I almost laugh when I get to see the tiny IM on D series motors.. Especially DXs. They're funny.

well if your going to do cams, throttle body etc i would say yes go for it, and like Siz said your going for an all out motor so i would sya go for it, they do em in Carbon Fibre too :P
