Thermal Intake Gaskets are designed to reduce the inlet air temperature thus resulting in colder air flowing in. Cold air is more dense than hot air and a denser intake air charge contains more oxygen which results in the potential for increased power and torque.

Each one of these intake gaskets will include a tube of "Hylomar Universal Blue Racing Formula" sealant. The use of OE inlet manifold gaskets is not required with the Cosworth Thermal Guard Composite Intake Gasket.

Cos does it again with these spacers... THE HEAT STOPS HERE! Just rebuild my motor from the heads up. Spend the $$$ get better than OEM gaskets. COLDER AIR = MORE POWER. Keep that intake isolated and keep your charge air colder.

    Does this kit require longer bolts to install? As opposite to GrimmSpeed Cosworth does not recommend using this item with stock gaskets - is that become of a different material or something else?

    • A: You can reuse your OEM TGV bolts with these 3mm thermal gaskets. These spacers use the included Hylomar Universal Blue Racing Formula sealant rather than OEM style gaskets.
