Features & Product Details

Do you know what your intake manifold sits on?...a superheated boxer engine. If you don't know already, the cooler your intake air is the more HP your car will achieve.GrimmSpeed has presented you the answer to this age old problem, raising the intake manifold off the engine with their new real Phenolic Intake Manifold/TGV to Engine Thermal Spacer.

Phenolic spacers have been used for years by many other specialized automotive companies, but this is very new technology to the Subaru world.

What it does:
* Greatly reduces the transfer of heat from engine to intake manifold thus reducing heat soak.
* One of a kind true Phenolic material, not cutting board material like others.
* The cooler your intake temperature is the denser the air is which leads to more power
* 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.
* Direct bolt-on.
* 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 GrimmSpeed's Phenolic Spacer, your hand can be placed on the intake manifold without any issues.
* GrimmSpeed has installed both with and without OEM Subaru Gaskets and have had no issues with either way.They do recommend using 2 sets of oem gaskets however, one on both sides of the spacer.
* USA made

Package Contents:
1 Pair Phenolic Thermal Spacers
8 Longer bolts with washers

When installing on the Impreza Phase 1 you will have to cut your EGR tube in half and insert a heater hose between the halves of the EGR tube to extend it.

    Do you know if these will fit the 93-96 WRX EJ20G engine? If not, do you guys carry spacers that will fit those engines?
