Yeah, Teflon is not really a good insulator, if you think about it, if it kept heat transfer down, they wouldn't put it on the inside of skillets.

In the world of plastics fluoropolymers (Teflon) has a middle of the road thermal conductance. It is an excellent high temperature service plastic however wood only has about ½ the thermal conductivity of PTFE. But comparing Teflon to aluminum Teflon is 1000 times less thermal conductive.
Cork has about ½ the thermal conductance of wood or ¼ that of Teflon. So, technically a paper or cork gasket is going to give you far better insulating properties than a Teflon one of the same thickness. Or in the case of thermal spacers wood or paper fiber insulate 2x better than Teflon or nylon.

any body know of any space age material or coating that when the surrounding heat increases it "cools off"!!!! NASA must know of some thing, think "SPACE SHUTTLE".

Tomorrow I going to pull the spacer out. And see if it runs cooler.
I'm not sure it is teflon. But it looks and feels like it. When I start the motor the intake runners are the same temperature as the head. And the bolts that hold the manifold on. There is no water passages in the intake so it should take more time to heat soak. And as it idles you would think the incoming air would cool the manifold somewhat. Icing the intake picked the car up a solid tenth last year (when I had water a passage in it) I cut the water passage off but the manifold seems hotter than last year.

It's called... Ceramics...and it is an insulator. The only product that cools off when heat is applied is sodium.

Heres a link to the spacer. I didn't expect that but I thought it might help.
