GrimmSpeed Phenolic Thermal Spacer 3mm
Grimmspeed Phenolic Intake Manifold/TGV to Engine Thermal Spacers greatly reduce the transfer of heat from your engine to the intake manifold which in turn reduces heat soak. By raising the intake manifold off the engine you create cooler intake temparatures and the air remains denser which leads to more power.
- True Phenolic material, not cutting board material like others.
- GrimmSpeed has tested that it is also safe to run race fuel, E85, and methanol with the Phenolic Spacers.
- Cooler and Denser Instake Air.
- USA made
- Greatly reduces the transfer of heat from engine to intake manifold thus reducing heat soak.
- The Phenolic Spacer will conduct 300-900 times less heat than the OEM steel gasket.
