Air Control Valve???

I have no clue what it does, I know it is an emissions thing, and helps with afterburn, and deceleration.

So no one makes a plate for the TII? I was trying to find it on RB's web site, but couldn't. I guess I can make my own.

Mazdatrix lists the same part for both N/A and TII last I checked, but they say you have to do something with the vacuum lines, but I don't think they say what. Trial and error has worked pretty well so far. lol

ok should i do this stuff to mine?? does it help much?

by the way what is this block off plate??? is that a plug? https://www.nopistons.com/forums/pub...R#>/mellow.png

/\ /\ That is the plate for a NA /\ /\ https://www.nopistons.com/forums/pub...#>/biggrin.png

Racing Beat sells them for $6.

Mazdatrix says you need to add a vacuum fitting to use one on a TII.
