GrimmSpeed Phenolic Thermal Spacer 8mm
Subaru Models (inc. 2004+ STI / 2002-2014 WRX)
Features & Product Details
RallySport Direct proudly carries quality aftermarket performance enhancements and solutions brought to you by GrimmSpeed.
These are the GrimmSpeed Phenolic Thermal Spacers. These thermal spacers have been designed to absorb the heat that generates between the intake manifold and the engine block. When running the factory gaskets only, the intake manifold can get very hot to the touch, and that unnecessary internal heat gets cycled back through the engine leaving much room for improvement. GrimmSpeed has come up with a great solution by creating a set of phenolic spacers that are available in a variety of thicknesses to absorb that heat to drastically reduce the transfer of heat from the engine block to the intake manifold. The result is a 1% increase in horsepower for every 5 degrees of heat reduction.

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.
Good item , don't miss to order all the gasket you need for install this item
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.

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.
