A.I.R. has tubes in the exhaust manifold. Those aren't for A.I.R.

Im asking what is AIR injection and if those are the little tube above the stock exhaust manifold for the emissinon?

Yeah, should be the tubes going into the exhaust from the air pump. It's injecting fresh air to get the exhaust gases to keep combusting after the exhaust valve. That way there's less raw gas in the air.

If your truck originally came with them, yup. 'Specially in california. You'll need the E.O. number which is the executive order by the California Air Resources Board which certified the part does not measurably increase emissions over the stock part.
