5mm thick Cotton Phenolic thermal inlet manifold gasket. The gasket has a bore diameter of 32.5mm please state what bore diameter and profile is required when ordering so that we can tailor the gasket to suit your engine model.
An ideal accessory for anyone installing one of our bike carb/throttle body conversions, home fabricated inlet manifolds or turbo inlets.
The Cotton Phenolic inlet manifold gasket acts as a barrier stopping heat transferring from the engine block through into the inlet manifold. Stopping this heat transfer results in a cooler inlet charge temperature and in doing so increases engine power in much the same way an intercooler does, except this is able to benefit a turbo and non-turbo setup
