  • Blocking the AIR ports on a 3x00

    I want to block off the ports coming out of the heads on cylinders 1/3 and 2/4 on my 2000 alero 3400. Don't worry about emissions or anything, as it is going into a Fiero that doesn't see the street very often anyways. I figured somone on here either made caps, or knew where I could find them. BTW, these are GM's excuse to an AIR injection setup right?

    Easy to do Justin.... just remove the fittings from the heads and replace them with 1/2-20 x 1" set screws, preferably stainless steel if you can find them. I believe it's a CA emissions engine.

      It was also for Northeast emissions as well. The AIR system is only "on" for 2 minutes when you start the engine cold. So performance wise it doesn't affect anything.

          I did something rather different but still the same idea.
