Best flowing intake mainfold.

[carlosamador16]

I am building a F22A4. What would be the best flowing intake manifold out of all the Honda engines that would bolt right up? Basically, something I would look for in a junkyard.

[Leung]

a port matched gasket with the H23 plenum attached to the A6's runners would be the best bet.

while it's out still don't forget to clean everything on the inside of carbon and all that jazz.

[carlosamador16]

Definetly gasket matching whatever goes back on. Thanks for the reply.

Tig welder says otherwise..

Lmao..

I totally kidd..

H23 upper, A6 lower, doublestack spacer, then gasketmatch/port slightly.

Ill tell you from expirience you will love it on an a4.

Did you do that yourself? Or send it somewhere to be done?

a lot of sweat, beer and 1 week of hard work
i saved $300 though

[WiKKeDV16]

What kind of beer?

The quality of the cerveza determines the quality of the port work..

Quality booze is key..lol

H22 and H23 intake manifolds the same?

[cloudasc]

H22 and H23 intake manifolds the same?

Upper manifolds are the same, throttle bodies are different.

[AbsurdNY]

Upper manifolds are the same, throttle bodies are different.

No you are wrong. The plenums and the throttle bodies are the same between H22 and H23's. The runners are different. The H22 runners will not fit on F series heads while the H23 runners will.

as far as the beer CORONA

as far as the TB w plenum

u'll find that even on the h23 mani, which has a p14 stamped (p14=h23)
the plenum will say p13 (p13=h22)
