Re: [TECH] Evolution tuning heatshields

[Dan Bubb <jdbubb@ix.netcom.com>]

Just a thought, but on the 8V the intake ports are angled up relative to
the rear face of the head and also the manifold mounting bolts. So, if
you install a 1/4" spacer you will cause a port misalignment. Cooler
air, but less flow.
Sounds like a waste of time to me.

It is make of a a non-conductive material that insulates the intake manifold from the heat in the head, thus keeping the intake manifold cooler, which transfers less heat to the incoming air charge resulting in denser, cooler air which = MORE HP!!!!
