What is it?
I removed this from my 1984 inline 6 and am not sure what it is, or what it does. An emissions thing maybe? Any help would be greatly appreciated.

A.I.R. injection air tubes. Allows fresh air to complete combustion before the tailpipe.

I am old enough to say this
 Back in the day everyone cut these and crimped them. Now everyone wants them back, so it looks Original.

Re: What is it?
There is or was a belt driven air pump that connected to those pipes. The AIR system is only needed if you are in a strict emissions area and your truck is still subject to emissions inspections.

Re: What is it?
Yep, the air pump is still there. I do live in a DEQ strict area so I'm planning on keeping it. Any idea what type of metal the tube is made of?
