Cosworth Phenolic Thermal Spacer 3mm - WRX 2002-2014 / STI 2004-2017 / More
NOTE: This product number has been discontinued by the manufacturer.
Thermal Intake Gaskets are designed to reduce the inlet air temperature thus resulting in colder air flowing in. Cold air is denser 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.
No customer comments for the moment.
