SKU: 019001

Spacers

Greatly reduces the transfer of heat from engine to intake manifold thus reducing heat soak.
True Phenolic material, not cutting board material like others.
For every 5 degree reduction in temperature, increases power by 1%.
The cooler and denser the intake air that the engine sucks in, increases the amount of air that can be mixed with fuel thus increasing efficiency.
When running the oem gasket only, your intake manifold gets very hot to the touch, enough to burn your hand. When the oem gasket is replaced with our Phenolic Spacer, your hand can be placed on the intake manifold without any issues.
