Phenolic transition spacer for VAG 1.8t large port to small port - set


10 mm transition Phenolic spacer for VAG 1.8T large port to small port and small port to large port intake manifold

Phenolic inlet manifold gasket for your Volkswagen 1.8t engine car like Audi S3 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. It fits to cars with small port head and with large port inlet manifold. Our phenolic spacer for Audi and Volkswagen 1.8 20VT is perfect fitted item.
