My take on Jet-Hot coating was that they do not allow the heat from the
headers to radiate outwards as freely, thus lowering the engine bay
temperature. This in return allows the car to breathe cooler,denser air,
thus burning more efficiently, with more possible HP as the result. Am I
wrong on this? I have never used it before, but was planning on using it
on the Late Model Stock car this next season.
