Help Air injection on Exhaust Im removing my air/smog pump. Does anyone know the thread size plug I need to delete these on the exhaust manifold. I wanted to buy the plugs for a few dollars rather than the kits on ebay for 35 dollars any help appreciated. Tommy

Supposed to be M22-1.5 but on one my cars those didn't fit so I think it might vary slightly by year. If you can just take piece of the smog pump piping you took out of the manifold or header to the hardware store and match it up.

Thanks For sure. My 95 (in sig) with the 383 was a late-model 1995 (lots of the parts are stamped as having been made in January/February of 1995). It required using a '96 dryer for the AC. The 95 unit was totally different.
