Need some input on reworking my stock s4 intake manifolds. I posted in the racecar tech section, https://www.rx7club.com/race-car-tech-103/manifold-tech-discussion-405896/ .

 

Looks a lot like an FD UIM to me... thought about plonking on of those on?

 

duz it really?? hmmm, ive never even seen the FD UIM, ill have to take a look. thanks!

anyone have any ideas? links? opinions? i tried doing some research but i cant find anything about intake plenums other than how to build one
