...I have no pic of it...but it's simple...put the h22/23 plenum where the f22 plenum was...put the butterfly spacers inbetween those...it's basic remove one and put the other one where the old one was...it goes on one way, pretty basic.

a6 runners
gutted butterflies..
just add h23 plenum

pic: what else you want?

What does gutting the butterflys really do for power??

I have a H23 Plenum sitting at the house..waiting for a h22/h23 TB..When I get it I will be swaping it onto my A6..Just wanted to know I'f it would be worth it to remove the butterflys??

PS...I really don't want to double stack the intake eather...

no for for stock

yes with high performance mods

double stack for torque (bottom end)

no stacks at all for hp (top end)

h23 runners are shorter A+ use it if u have it.

A have a A6 so I'm just going to add the H23 Plenum and TB to it with the Butterflys intact (for low end) ..couple that with a EGR/Air Boost Block off and I'm good....

You want pictures of an h23 plenum on an a6, and also a doublestack, here you go:

Notice the double-stack, butterflys on top, gutted spacer on the bottom:

Here is a couple pictures of the h23 plenum on at runners:

My Engine Bay with it installed:

The most important thing is how you route coolant lines, in throttle body, out fitv, in right side of iacv, out left side of iacv. Also make sure your tps screw is tightened all the way, and your air boost valve vacuum line is connected to the the intake pipe, not the plenum. Oh and use the nipple on the thermostat housing to bleed any air bubbles in your system. That should help you avoid most idle issues.

As for the butterfly's, leave them in and working, I drove around with the butterflys open all the time, and the loss in low end torque sucks for daily driving. Removing them really isn't beneficial unless you plan on making power of 7k rpms, and if your going to be revving that high, you might as well remove the iab plate alltogether and tune.

i second the loss of torque low end for the butterflies open.

I ended up hooking them up via vacumn. still opened but oh well..i loved how it sounded HIGH end.
