Description
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

Put these bad boys on my 06 sti with a TGV delete and a top feed conversion. The car is definitely much less affected by heat soak. It's pretty obvious after long periods of driving. Great, inexpensive upgrade, and one that should definitely be done in conjunction with any TGV delete project!

Keeps my Intake Manifold nice and cool
z.emerick41643 1 year ago
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!

Works great on legacy gt!

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.

  • Q: Clearance and tune  ADingle 3 months ago

    Answer

    Will these work with an STI TMIC? Also, are these direct install and go or is a tune needed? Thanks!


    • A: These should fit with your intercooler. No tune is needed. Just install and you are good to go.

  • Q: PW TMIC  mattcowle 2 years ago

    Answer

    i have a 2011 wrx with a Process West TMIC .. will this work in terms of clearance? thanks


    • A: I can't speak for compatibility with other TMIC's but they do work well with the OEM intercooler. Mike


      GrimmSpeed 2 years ago
    • A: There will be some issues, as the Manifold will now sit 8mm higher and as a result could create fitment issues. This will be an issue with any part that is related to the manifold as everything gets moved up vertically by the distance that equals the thickness of the spacer.

  • Q: Fitment   midnightprince304419 3 years ago

    Answer

    Will these work and still have enough clearance for the Perrin FMIC? 2002 WRX


    • A: We have not tested fitment, but with this unit everything will shift up 8mm. So you can look at your set up and see if you will have sufficient clearance.

  • Q: Work with Coswoth TGV.?  Ian 3 years ago

    Answer

    Hey , I have cosworth TGV Deletes with the Cosworth Intake manifold. Will these fit ok.? My main question is will this raise the manifold enough to enable me to fit the AVO 3 inch intake. I bought the AMR hard unit before and didnt fit with the cosworth manifold as not enough clearance, Really need to fit a 3 inch intake.


    • A: They will fit, but the only thing we dont know about is the hood clearance from the manifold or if that will be enough to fit a turbo inlet.
