Cosworth Phenolic Thermal Spacer 3mm - WRX & STI & LGT & FXT 2002-2014 / More
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.
