Which Intake Manifold to get,F22A6

[p99gt2003]

I have an F22A6 and have been looking at what others are doing to intake manifolds,which intake manifold should I get to bolt up to my F22A6? I have found 2 close to where I am only problem is dont know which one to get, the Prelude 2.3L or the Prelude 2.2L V-TEC they have both....please help.

you can get an h23 IM or just keep the a6 IM which flows very well already

so keep my old a6 im and p&p it? and what short ram air to get or does it really matter? I've seen short ram airs on ebay for $30-60 or I can get an AEM for $120

The H23 manifold is a significant upgrade. The H23's plenum will bolt to the lower half of the F22A6 manifold, which is supposedly the best combinaton... but that's only a theory, as it has never been tested on a dyno.

As for a short ram, the pipe doesn't matter... but the filter does. You're going to want a proper AEM or K&N filter. You can get a cheapie pipe. That doesn't matter at all.

A6 with a bit of cleanup would be best. Your efforts with an H23 most likely wont be rewarded unless you're doing a serious build. However, you could do something crazy like have an adaptor plate made to make a Euro R or one of the fancy K20 manifolds fit. I just had an adaptor plate made for my F23 to H23 IM. With CNC and an aluminum 3/8" plate you can do pretty much anything.

The H23 intake manifold bolts right on, and gives a larger plenum and throttle body in stock form. Significant upgrades aren't necessary to see gains with it. However, anything done to increase breathing abililty will most certainly make better use of it... as will a proper ECU tune.

you can also install a spacer to you a6 Intake manifold to make it bigger

even if it isnt the best, the egr ports are a little bit easier to service.

the f22b or a ( i cant remember ) has a much bigger tb bore than the h series. research it

get an h23/h22 throttle body and plenum (the plenums are very close to identical) and add a gutted IAB plate or blacktrax spacer under the stock one. this lengthens the runners which is good for the lower end power of the f-series. for high-end power, remove the IAB plate and bolt the h23 tb straight to the runners.

i believe you are thinking of the f20c, or s2000 throttle body which is much bigger than the h-series tb. it bolts straight to the h23/h22 plenum as well i have never seen an f22b with a bigger bore than an h-series.
