Anybody know the underhood temperature diffrence between coated and uncoated headers.

THANKS

Hotter than hell(uncoated) vs. just hotter than blazes.

Headers generate perhaps most of the underhood heat.

Jet Hot's website talks about actual header temps.

I would infer a significant decrease in U/H temps for coated headers. The amount probably depends on airflow out from underhood. Think old TransAm vents in the fenders.
