just wondering what you guys thought about this stuff for keeping the cab and engine bay cooler for the obvios benefits of comfort and power gains.

does the stuf actual help or is it just a gimmik?

 

I have tried it in the past. You will notice the header will not last on the street. In a race car it should be ok, but daily driving, I lost 2 headers with a months run time on them. Went with the jet hot type coating and never had a problem again.

bwaits:> Was your DP Stainless ?
Stainless should hold up longer and not oxidize, but they still get very hot.

Andrew:> There is no HP gain from this, just a big underhood temp reduction especially after stopping.

 

Ceramic coating is a little more expensive but it will last. Both will lower under hood temps.

The header wrap will dry out over a couple years time and fall apart, especially if it gets wet - driving in rain.
