Post pics of painted Intake Manifolds.

Biggest thing about regular paint or powder coating is that they usually retain heat. Not the best thing if you are looking for better performance from your parts. Specially the intake manifold.

If you want to paint or coat your manifold or block use something with a high ceramic content that is said to dissipate heat. Some high end caliper paints are made with such properties. Not as good as leaving a bare aluminum surface but it's better than regular paint and powder.

If your going to paint the manifold at least paint the bolts a differnt color. It makes it stand out very nice.

I did my 300zx valve cover and plenum with aluminum alloy siliver and it looks nicer than silver and stock but still very clean. I painted the bolts and screws black.
