Phenolic is a material used in the Aerospace and Electronic industry for its superior insulation properties. It has even been used by NASA during the space exploration as a heat barrier. Phenolic is made by compressing layers of resin soaked canvas while under heat. When cured, it has a brown grainy appearance which is commonly mistaken as wood. We use Phenolic in our carb spacers and adapters to stop the transfer of heat from the engine to the fuel system. Intake manifolds and aluminum carb spacers readily transfer heat through the carburetor heating your fuel which has an adverse effect on performance. Our Phenolic spacers and adapters stops this transfer, therefor lowering the fuel temperature.Pit Stop USA offers Canton 1" Phenolic Blended 4-Hole Carb Spacer Holley 4150, 4160 85-158 at low everyday prices.
