ENG: diy plenum spacer

[Chrisfrom1986]

F22a1 doesnt come with a spacer...

[Jon]

Yeah the F22A1s don't have spacers. That and they don't have dual runners...

[KeeleDesign]

well guys for those who want to get the most out of their intake, i also wanted to so i went ahead and did the double spacer, and found out its pretty easy upgrade.i tried to do this as easy as possible (using all onda parts)

tools needed:

1 12mm socket
2 3 cb7 compressor bolts
3 2 90' prelude compressor bolts
4 2 exhaust nuts
5 jb weld
6 sand paper
7 h22, h23, f22a6, f22b, spacer

first step: get a the spacer, remove butterflies, vaccum diaphram, rod that goes through, and fill in with JB WELD

second step: sand the JB weld till the holes are smooth



third step: take two exhaust nuts and screw them in the bolts in the lower manifold, and take both bolts out



fourth step: put the spacer first, butterfly spacer next and finish with the upper plenum, insert the prelude bolts first to align everything, and then the accord ones



fifth step: tighten everything and smile (some hoses u'll have to change, i didnt)

was this manifold sandblasted?

[PR CB7]

was this manifold sandblasted?

$.99 paint man

[KeeleDesign]

ohh... thats kewl, i was just curious what mine is going to look like when it comes back from being blasted.

[Flatline]

i wish i would have seen this a couple months ago. i could have made out with one of those spacers free. had the manifold already out of the car when i saw it. i have to see if it's still there.

I have a a1 plenum what spacer do i get? which one would fit?
oh yeah I love the DIY

[Jon]

I have a a1 plenum what spacer do i get?

Neither.

which one would fit?

None.

If you have an A1, you are going to have to upgrade to a H23 or A6 intake manifold that has dual runners because the A1s and A4s are both single runners. And no vehicle came with a single runner spacer nor does any company make a single runner spacer.

Hope that clears things up for ya.

Dangit I knew I should have went into more detail...

[PR CB7]

Dangit I knew I should have went into more detail...

why u say that

[Jon]

why u say that

Because I typed up this really long response with a list of intake manifolds they could use and all that and said to myself "wow, that's not a simple answer for a simple question..."... that's why I said that.

is there a diy on how to remove the IM??

[Jon]

is there a diy on how to remove the IM??

Not that I know of, but it's pretty straight forward.

Undo like 7-9 nuts (can't remember), pull off a couple of vacuum lines, coolant lines, and that's about it. A Haynes, Chilton, or other repair manual would be helpful.

Maybe when I do my intake mani in then next few weeks, I'll snap some photos and throw a DIY on how to remove and install one. No promises though...
