This is a custom designed and manufactured phenolic spacer constructed of G10 material. Included with this product is everything to install: Spacer, gaskets, stainless steel studs and hardware. 

This spacer is used to decrease heat transfer from the head to the intake manifold, thus reducing intake ambient air temperature. Added bonuses are decreased cool down time of the intake manifold during engine off and intake manifold spaced further away from the turbo provisioning more space for a heat shield to be fitted. 

Can also be used if your custom mount still does not allow
