I have a 2.0L 1990 Turbo Sunbird and have a question about intake setups other than the stock air box. I just wanted to just stick a cone where the air box was or make it come straight off the turbo.The question is; there is a hose coming from the camshaft housing cover into the air box, I was wondering what people do with this hose when running a CAI/WAI setup.

The hose coming off the cam cover is the inlet side of the PCV system. you can just put one of those breathers that looks like a tiny air filter on it.

where might I find one of those?

anywhere really. try the "performance" isle at your local parts store if you want one right away.
