Since I am in the process of rebuilding the motor in my 88 IROC I was wondering how much of a difference it would make in my emissions if I removed the A.I.R. pipes and related parts. If I do remove the A.I.R. manifolds I have some other ones to use so as to make it easier to convert it back later.

the way i understand it, it only robs around 5-7 hp. if you dont have emissions where you are, yank it out. i would pull mine out, but i have hardcore sniffers in nj.

 

I dont know how much it does for emissions, but I can sure get to the plugs and plugwires now. I removed my a/c compressor and my smog pump. And the a.i.r tubes are history.

 

If you have the time I would, but I removed mine when I installed my headders. Just make sure you seal the manifolds up, the sound gets old after a while.

 

Where? On the intake manifold or something?

And is there a tech article somewhere describing what all can come off?.....like that mushroom looking thing with 3 hoses in it....what the hell is that?

 

yes you can take the "mushroom looking thing" off. Also take the smog pump, all the hoses running to it and the air tubes also.

You will have to get a shorter belt. You can also remove the a/c compressor and its componets. But you will have to have a a/c delete pulley from GM.

 

If you have a good running engine you can pass emissions without the AIR pump.

 

I would prefer to keep my heating and AC capablities, so I won't go quite that far. However, when I was checking it all out yesterday, it looked as though there was some hose coming out of the back of the serpentine setup (not sure of the component), but can I just plug that hose or something (although it looks like I'll need something the size of a golf ball to do it)?
