Having just finished putting headers on the ITB Rabbit, I have been thinking about the intake getting heat soaked and was wondering what others may be doing. Here’s some idea’s I’ll throw out.

Sheet metal box around the intake and duct some fresh air to create an air barrier, is this legal?

Header wrap, I have heard arguments for and against this method.

Header coatings, any recommendations?

Insulating nylon intake gasket to help keep head heat separate from intake, anybody heard of such a thing?

Reflective paint on the underside of the intake.

Anybody have any other suggestions?
