M62 Supercharged Phenolic Spacer

Running a M62 Supercharger? If you are then this is something that you NEED to have. When the supercharger starts to make boost(PSI), the amount of heat that gets transferred to the intake manifold can be greater than 40 degrees. A heat exchanger does a good job of keeping the pressurized air cool going into the engine, but after a few runs the heat exchanger gets heat soak itself. A phenolic flange between the supercharged and intake manifold will greatly reduce the heat transfer resulting in more power, for a greater period of time.

*Comes with gasket
