What does A.I.R. stand for on 88-95 5.7L TBIs?

Looking in Jegs for a set of headers for my truck (92 K1500, 350 TBI), and the choices for my application said With A.I.R. and w/o A.I.R. What does that mean?

I've never heard of this.

Never mind. I found out what it was. Its a secondary air intake, has a pump that pumps air into the intake I think. My truck doesn't have it.

It stands for Air Injection Reaction. It pumps air into the exhaust, which helps unburned fuel burn completely inside the catalytic converter.

Yeah, I found that out like 10-15 minutes after I posted it, lol. Its cool becuase those headers are like $15 cheaper then ones that are made for vehicles that have the A.I.R.

Thanks for the reply though.
