Does anyone have this on their car? Is it really helpful, or is it just another aftermarket add-on.

There's a solution to most problems...even when it ain't a problem.

I was a cynic when I was 30ish.....it don't get any better with age.

I don't think it'll do anything really on a teener, but maybe on a 911? Maybe because their damn exhast wraps around and sits under there?

anything that deflects heat from the engine helps cooling the engine.

having said that, i have never seen any actual measurements showing any improvemets (lower engine temps) when using the Heet-Sheet ...
