Phenolic Spacer - Intake Manifold

[Bug_racer]

You need a gasket, or sealant, each side as phenolic is hard and non compressive, and their may be leaks if installed dry.

There is a few different types of materials that are used , some require sealant others dont , you need to read the instructions in the packet !

OK didn't realise, I did a lot of work in the late 90's with a Starion and phenolic, and all I could find after extensive searching was hard, brittle stuff. Perhaps that has changed, or perhaps they are using materials other than true Phenolic.
