GrimmSpeed Phenolic Intake Manifold Spacers (WRX, STI, LGT, FXT)
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. We present you the answer to this age old problem, raising the intake manifold off the engine with GrimmSpeed's new real Phenolic Intake Manifold/TGV to Engine Thermal Spacer.
FEATURES
- 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 air 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.
- GrimmSpeed 3mm Subaru WRX STI Phenolic Thermal Spacer
- 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 our Phenolic Spacer, your hand can be placed on the intake manifold without any issues.
- We have installed both with and without OEM Subaru Gaskets and have had no issues with either way. We do recommend using 2 sets of oem gaskets however, one on both sides of the spacer.

GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered aftermarket products. On a more personal level, we are a group car enthusiasts who are working our passions in the lovely city of Minneapolis, Minnesota. Our bread and butter started out anything Subaru. However, after growing our team and engineering expertise, we started developing products for Mitsubishi, Ford, MazdaSpeed, and Hyundai markets. We are a true garage start-up (single stall townhouse garage in Maplewood, Minnesota) and we've been lucky enough over the years to be able to turn it into exactly the business we had dreamed....actually, much more. We have a wide breadth of product offerings including; intercoolers, exhausts, intakes, gaskets, engine pulleys, phenolic spacers, boost controllers, and many more.
