I run the natural aluminum 2x4 Ford intake as well with no discoloration.

Tom: My factory dual four manifold did not discolor, it's the paint that discolors on the others. There's no paint on the natural finish aluminum ones.

Does the aluminum intakes discolor like the painted ones do, if you don't block off the center exhaust valve ports?
