Phenolic Spacer question if any?

[Jrok25supra]

i used to own a 97 Ford Probe GTS and I installed Phenolic spacers for the throttle body and intake manifold. If you dont know what it is it a special material used to put between the head/manifold/throttle body to keep alot of heat from transfering from the motor to intake for cooler air intake. I only know the Civics and Mazda KL series motors to have these. They work great during the winter and good during the summer. After driving for long periods of time I could put my hand on the manifold and it would be ice cold.

I wanted to know if there was anything like this out for sale or at least in development for any of the Supras. If so this would be great. I'll post pics when i get home.
