A.I.R. tube plugs

I know this has been asked before but........What do you use to plug the A.I.R. tubes with on a set of headers after you cut them off? I can't remember. :confused: Edelbrock T.E.S. BTW.

I think RobP used bolts on his. I would cut some bolts off real short and weld around them to make a tight seal.

I threaded the openings on my SLPs and ran bolts down them, measured the bolts, and then cut them so they did not interfere with exhaust gases. In hind sight, I would have cut the air tubes, welded the holes and then had them coated. My bolts eventually backed out (even though they were coated in place) and allowed fresh air to screw with my O2 sensor. My holes are welded shut now.

It's a pipe thread, like 1/8 NPT or 1/4 NPT I think. Whatever you do don't use brass pipe plugs, they will get hot and after a while blow out do to the softening of the threads.
