Suitable for use with the CSF Radiators high performance chargecooler intake manifold this thermal rejection spacer fits between the intake manifold and cylinder head and is designed to reduce heat soak from the engine into the chargecooler. This can be particularly beneficial to drag cars where they may be sat in a staging area between runs. In some tests intake temps were reduced by 77°F (25°C) at the start of a run compared to using a standard gasket.Reduces heat soak from the engine to the chargecoolerCan reduce intake manifold temps by up to 15%Self sealing, no other gaskets requiredAs strong as aluminium and capable of withstanding temperatures up to 1100°F (593°C)Ideal to use in conjunction with the CSF Radiators high performance chargecooler intake manifoldNot suitable for OEM intake manifold
