Features & Product Details

When it comes to selecting the right intercooler with maximum cooling and minimum restriction, then check out this GrimmSpeed unit. As air is pressurized by your turbo, it heats up, not because of the heat of the turbocharger, but because when they’re compressed, the atoms in the air are forced closer together and as a result, move faster and have more energy. That energy manifests itself as heat. The more heat we can remove from the system, the denser the air becomes and that’s what helps eliminate pre-detonation, or ‘knock’, allowing for increased output from your system. Your OEM TMIC does just fine at stock boost under normal use, but as soon as you start putting some real heat into it with higher boost or harder use, it heat-soaks beyond recovery.

These units have been engineered to find that perfect balance with heat transfer and pressure drop. They began by laser scanning an OEM TMIC to plot the mounting points and space claim in CAD with pinpoint accuracy. At the same time, they designed a custom bar and plate core with overall dimensions, fin density and fin types that would provide the insane heat transfer area they require with minimal flow restriction. With core size nailed down, they got to work designing end tanks that offered smooth flow, perfect fitment and even distribution of the hot charge air through the core. Countless revisions were tested in flow simulation before they finally found exactly the characteristics that they wanted. From there, 3D printed prototypes were used to confirm fitment and we began work on manufacturing details in preparation for verification testing and production.

Each and every end tank is cast from the same CNC machined mold, ensuring not just dimensionally perfect castings with an amazing surface finish, but also excellent repeatability. They designed tabs to be laser cut and CNC bent from 5052 aluminum, selected for its ductile nature, to ensure that the bending and welding processes don’t compromise their integrity. And this will allow for stock TMIC bushings. These are also designed to work with your stock y-pipe. Of course if you don't have one they've also designed a cast aluminum y-pipe kit with a 4-piece 5-ply silicone couplers and t-bolt clamps for each connection.

04-05 Forester XT require a STI BOV and STI BOV recirculation hose.

WRX and Forester models will need OEM STI or GrimmSpeed Y-Pipe Kit

Quick Delivery/Minor Fitment Issues 7 months ago
5out of 5stars

The product was delivered quickly. During the install, there was an issue at the shop with fitment. The shop ordered an appropriate adapter to finish the install. It was probably something I should have checked into so not the fault of RSD. Very pleased overall.

Replaced my OEM TMIC with Grimmspeed. Well built an looks good. Its moderately heavy and a pain to install since your semi leaned over. Fitment is tight. Item was well packaged an shipped quickly. Pleasure doing business with RSD again.

GrimmSpeed Top Mount Intercooler on 04 Forester XT 4 years ago
5out of 5stars

The unit it self is great. The only issue I had was the lack of info about the installation. Some people said that you can still use the OEM Y pipe, but if want to save time and pain, use a silicon after market Y pipe.

QUESTIONS & ANSWERS

  • Q: GrimmSpeed intercooler splitter  Chris1 month ago

    Does this include the GrimmSpeed intercooler splitter? GrimmSpeed states it's included in 2015+ but I don't see it mentioned in the product description of the "what's in the box" video. Thanks in advance!
  • Q: 2012 wrx   schryba211 year ago

    Hello I have a 2012 wrx it has a cobb intake and cobb down pipe stage 2 tuned cobb and I was just wondering if I would need a retune after putting the grimespeed upgraded intercooler in
    • 0 of 0 people found the following answer helpful

      A:  No tune is required, but it is recommended. A tune will give you the most out of your upgrades.

  • Q: Upgrades on a 2006 Subaru WRX  Jacob 2 years ago

    Would this be enough for a blouch tdo6-20gxt turbo. I will be getting new 1050 injectors, 255 pump, cosworth air intake, turbosmart bov, boost solenoid, and a grimmspeed exhaust. Is there anything else I need to prevent engine implosion?
    • 1 of 1 people found the following answer helpful

      A:  This would be a great TMIC for your setup. Although a 20G is approaching what most would call the safety limit with the stock block, a good tune, an air oil separator, upgraded oil pickup and baffle, aluminum radiator, and good maintenance are all great steps towards making your motor last.
