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

GrimmSpeed Phenolic Thermal Spacer 8mm ( Part Number: 019001)
Perfect 1 year ago
Lucho71509
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.

Keeps my Intake Manifold nice and cool 4 years ago
z.emerick41643
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! 4 years ago

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.

Great Product 4 years ago

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

QUESTIONS & ANSWERS

  • Q: FP green Tomeii turbo inlet amd ETS TMIC, clearance or fitment issues?  aubreylanglinais2012864952 years ago

    I'm running a stock location FP green with a Tomeii turbo inlet and an ETS TMIC. Will the 8mm cause any alignment or clearance issues on a 2014 sti?
  • Q: N/A Intake Manifold & 3" Turbo Inlet  alexandertrojanowski174072 years ago

    I had the lucky draw of getting a block that wanted to let one of the bearings disintegrate, so now I'm going with a pretty substantial build. Since I can't really afford a wildly absurd turbo/rotated/fuel setup right now, I'm looking at snagging a Dom2.5. I'm curious if these would work with the N/A intake manifold while also allowing clearance for a stock location 3" turbo inlet. Thanks!
  • Q: PW TMIC  mattcowle5 years ago

    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

      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   midnightprince3044195 years ago

    Will these work and still have enough clearance for the Perrin FMIC? 2002 WRX
    • 0 of 0 people found the following answer helpful

      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.
