I have Jet-Hot coating on my headers (race/rally spridget).
Yes, it is nice.
Yes, it does protect against corrosion.
No, it is not a noticeable HP winner.
No, you can't touch the headers (the temperature may be a little
cooler, but it is still darn hot!)
No, I haven't noticed a significant difference in underhood temps. Note
there may be a difference, it is just that it doesn't jump up and slap
you in the face. (I mean in terms of engine temp, HP due to cooler air etc)
The footwell *seems* to be little cooler (the headers/collector - both
coated -
run immediately under the pedals. Some of the engine bay air runs down
the tunnel.
YMMV, Mike
