Yeah this has all been debated before.
In fact Im pretty sure Im one the first few CEGers to do this mod.
Thats my engine pictured in the group buy:


I wouldn't disagee with you, but who knows for sure with out actual testing.
I can tell you that (by touch) the heat was noticeably less.
I can actally lay my hand on the UIM after a two hour drive.
Im not gonna tell you I felt a difference in power (butt-dyno). Some people began powdercoating, I figured why not go a step further and ceramic coat it.
Does this help? Sure it does. Is it the best way to go about it? Probably not, Im sure there are cheaper methods as stated above. I was sposored by Jet Hot and had them do this. Along with my cold air intake, Y-pipe, etc.
