GrimmSpeed Phenolic Thermal Spacer 8mm
Subaru Models (inc. 2004+ STI / 2002-2014 WRX)
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 presents 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.
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

These spacers fit perfect on my 06 wrx. Great quality, installation is a PITA but not impossible. Haven't been able to test the temp difference yet as I am currently in the process of rotating my turbo. Great product though.

I had issues with my sleeved block radiating heat up through the TGVs, then my cosworth intake manifold, and finally my ic-throttle body pipe where my speed density sesnor was located. This caused incredibly high IAT temps on the dyno. Since installing this my temps are far lower and the intake manifold is never hot to the touch unlike before. I'd highly recommend this product!

I recently went with a rotated turbo and intake manifold. I needed a little more height to clear the pipe past the p/s pump and for the top feed rails to clear the avcs. Not only do they look great but the 8mm still cleared my hood. Amazing product highly recommend.

Fitment is good. maybe heat soak is reduced a little bit. And intake manifold is also less hot when you put this spacer.

Would the Verti bracket for the TMIC help with fitment, using the 8 mm?

A: No, the bracket will move the IC a bit lower. These are more meant for front mount set ups.

A: This spacer could help you with the clearance issues, but I would strongly recommend a FMIC setup. The reason being is that heat soak is going to be a huge factor here, with the FP Black being one of the largest OEM location turbos it is going to cause the TMIC to have fitment issues like you are currently running into, as well as major heat soak issues with the TMIC.

A: You may run into fitment issues. The 8mm is meant more for FMIC, with the 3mm you should be able to get the TMIC to fit properly.

A: One is 3 MM thick and one is 8MM thick, depending on what TMIC you are running you may have issues when running the 8MM spacer, we only recommend the 8MM for FMIC set ups.
