Ditto, they're perfect. Mine have their standard ceramic coating option, too, which lessens radiant heat spectacularly.

I will say that 1) installation is best done by someone with experience (unlike yours truly), and 2) the passenger side header does route close to the starter, but there is still enough of an air gap, I've never had an issue warm or hot starting the car.
