Air injection question

I thought it was called the 'air injector manifold' or something like that. Aftermarket ones are available at any auto parts store.

P.S. For the love of all that is good and pure, just leave that A.I.R. system junk off your engine! Best think I ever done when my car was bone stock was to get that garbage off my engine!

It's called an AIR Pump Check Valve. O'reilly's or Autozone should have them.

The service manual refers to them as 'air pipe extensions'. I'm pretty sure those are GM/Olds specific parts and not available aftermarket. Those stupid little things are what protrude into the exhaust port and hamper flow. Stock resto or not, leave them out. It will be our little secret. No reason to choke down an already choked engine any more than neccesary and you would still have everything look stock on the outside.

I have a VIN 9 motor in my shop. I sold the AIR set up off of it but believe the part you need is still there. Let me check and I'll get back to you.

Can't see how they would. If by some freak thing they do though, then just slap em in.
