I have a few different 6.2 intake manifolds sitting around and figured some people might not know what options are available, so here's pics of the ones I have. For the newbs, these are all non-EGR intakes. First, is the normal dual plain intake, found on most non-EGR trucks. Second is a chevy truck single plane intake pictured next to a hummer 6.2 single plane intake. The civilian versrion is on the right and the hummer one is on the left. I'll let the experts explain why one is better than the other but here's the pics.
