Underhood temps are extremely cool with the HPF turbo kits and this is one of the reasons why. Go to a track day and check out the underhood temps after an HPF M3 does a 30 minute session. Quite amazing.

What's the temp difference between coated and non-coated?

My understanding is the issue with ceramic coating is that the metal will fail a lot quicker since all of the heat is trapped inside of the pipes. Any idea on the decrease in lifespan?

I'm asking because you guys probably have more experience with this. Just wanted to put that disclaimer out there so there are no mo' deleted posts.
