I want to reduce the heat soak on my intake. I haven't checked the temperature of my stock crossover, but I don't think I can grab and hold my JR intake after cruising awhile. Running 1.6, JR intake, driver side headlight air duct, Koyo 37mm, oem header with oem heat shield, factory air guide in the bumper, missing the oem under tray though.
So, I've been considering the $33 roll of this to cover the JR intake and oem crossover.

Is there a better solution than that material? I'm also considering an ARC crossover (which I would cover in gold too), does anyone know how that would affect heat soak? Is aluminum more prone to heat soak than plastic? Does it cool off faster after turning off the car? Any other ideas to reduce intake temps or under hood temps in general? Phenolic intake gasket?
