new guy - What are these?

Ok so I'm new to CJs and engines in general I guess. Does anyone know what these are? What do they do? And most importantly, do I need them?

They seem to be hollow and the bolts have a hole in them with lots of black exhaust stuff in them. A guy at work with a 78 CJ7 said he'd never seen them and had no idea what they were.

I think it's the supports for the A.I.R. injector system.

They usually are welded on...

They are useless now.

It's for injecting fresh air into the exhaust system to help the catalytic converter.

Yea I figured it was something like that and that I didn't need them anymore. Thanks John.

Some of the later replacement manifolds have plugs that can be removed so the will work on either system. If it has a nut and you can get it out then you should be able to get a plug.
