    99 trans am secondary air injection

    Just wanting to see if anyone knows where to get the block off plates for the sec air inj system besides making your own, and whether or not it is worth doing performance wise? Thanks

    Thunder Racing sells air and egr block off plates. If you're in California and they do a visual emissions inspection it might get you into trouble. No performance gain IMO, just cleans up the engine bay.

    It does nothing for performance, the only gain would be if you took it all off the car to save (minimal) weight.

    Thanks guys. I pulled the EGR off, but I guess I'll leave the secondary air injection alone. Again, thanks.
