Meticulous Engineering, Unparalleled Craftsmanship

Replace that undersized, plastic stock intercooler with a GrimmSpeed Top Mount Intercooler Kit, featuring cast aluminum end tanks, large bar and plate core and TIG welded construction. The factory FA20dit TMIC is well-suited for stock applications, but when boost levels are increased, the higher post-turbo air temps contribute to pre-detonation (or 'knock') and loss in power. The GrimmSpeed intercooler is designed to keep charge temps consistent during aggressive driving so that the rest of your parts can work to make power.

QUICK SPECS

  • 13.1in x 10in x 3.75in Cross Flow Core - careful balance of high heat transfer and low pressure drop
  • Cast Aluminum End Tanks - featuring machined splitter mounting features
  • 5-Ply Silicone Couplers - custom molded and reinforced for demanding environments
  • Fully-Integrated Two-Piece Splitter - collects air from the entire width of the scoop and feeds it directly to the core
  • Water Meth 1/8 NPT Bung - Cast into the outlet end tank, CNC machine tapped and plugged for future use
  • Vibration Isolation Mounting - protect the intercooler system from fatigue due to vibration by reusing the factory mounts
  • Cleaned, Inspected and Sealed Prior to Shipping - prevent motor damage due to foreign matter

WHY GRIMMSPEED?

The GrimmSpeed engineering team has a history of developing the highest performing Top Mount Intercoolers available and the 2015-21 WRX fitment is no different. This intercooler was in the testing and revision phase for over a year, as continual improvements to performance and fitment were found. The GrimmSpeed kit offers a perfectly fitting intercooler assembly, along with a custom 5-ply silicone throttle body coupler and hi-torque stainless steel clamps. Each kit also includes our unique two-piece splitter design that replaces the factory engine cover with a splitter design that's made to fit the larger core of the GrimmSpeed TMIC. The performance of any Top Mount Intercooler is only as good as the splitter that's directing air through the core and in this area especially, the GrimmSpeed team nailed it.

  • High Efficiency and Flow - Other manufacturers focus on cooling without understanding the damage that high restriction can do to a cars ability to produce power.
  • Two-Piece Splitter Design - Other manufacturers repurpose or modify the stock engine cover. GrimmSpeed has replaced it entirely with an innovative two-piece design.
  • Optional Upgraded Charge Pipe - Use of the GrimmSpeed Charge Pipe is optional, allowing you to upgrade at your own pace.
  • Designed and Manufactured Locally - Ensuring repeatable quality, clean components and consistent assembly

Each intercooler uses two unique end tanks. The first accepts the hot charge air from the turbo and feeds it to the intercooler core. The second receives the cooled charge air from the core and delivers it to the throttle body. These end tanks are precision cast and machined right here in Minnesota. Following inspection, end tanks are welded to high density bar and plate intercoolers before the entire assembly is pressure tested, cleaned and sealed for shipment. 5-ply silicone couplers hold their shape in extreme conditions and ensure that charge air makes it to and from the intercooler with no trouble. Splitters are laser cut from aluminum sheet and CNC bent before being assembled and powdercoated with a durable texture black finish. Stainless steel hardware secures the splitter to the factory hood scoop.

PERFORMANCE

We tested the OEM TMIC, GrimmSpeed TMIC and a leading competitor TMIC in a back to back to back comparison and used our multi-sensor data acquisition system to evaluate temperature deltas, intercooler efficiency, pressure drop and more. Below is a chart showing cooling efficiency between the three.

Best TMIC on the market

For anyone looking for a tmic for your 2015-2021 Subaru WRX and where to pick one up. Just buy it here at WRX daily.
Great price very fast shipping and the best customer service you can get! Very easy to install and a great fit. You can install it in about 1 hour!! I gave it a 4 Star because the push bulb trim for the hood/inter-cooler shroud was way to big it kept on falling off. It wasn't WRX daily fault, it was packaged like that from Grimmspeed. I contacted Grimmspeed and still waiting for a response almost 3 weeks now.. I just had to do some modifications to make it work.. I want to thank Justin and the team for helping me get the parts I needed and sent it to me very fast!! WRX Daily will be my new go to shop, for all my car parts!!!

It’s an intercooler

Nice upgrade to stock, build quality is dialed in. All the welds are done well and the finish clean. Install was very easy. I have not experienced any heat soak but haven’t had the chance to push the limits just yet. Waiting on a few parts to finish my build and a final tune. Happy with my purchase.

This is the one

First of all customer service is top notch🙏, thank you for helping me returned a previous TMIC. Grimmspeed TMIC is very easy to install, tooked me less than 10mins. Quality is superb, been driving my vb for 3 days now without a tune. I noticed increased of 2 psi, increased throttle responds and decreased of air temperature of 20 according to my Cobb AP. Scheduled a tune in two weeks, hopefully it will get a full potential out of it.

5 Stars with upgraded tune

So I added this with a CatBack exhaust and got some great flow. I had the tune updated and picked up a solid difference. It is a nice well made product and arrived promptly. I am very happy with my purchase.

Very nice product - May need some tuning if not stock.

I added this (and only this) to a Cobb Stage 1 setup with an axle back. The combo of the two flows WAY too much for the Cobb Stage 1 tune. I am doing a pro tune on it now and am expecting good results. I am not there yet. It may work in isolation but with anything else you will need to tune.

I will update and the results should be good but be careful if you have any other mods.

Thank you for your review! You're correct, although not required, it is definitely recommended to get a tune after the installation of a TMIC to maximize the benefits of the upgrade. We hope that the pro-tune makes your review of the GrimmSpeed TMIC a 5/5!

Grimmspeed--Top Notch

I coupled this with a few other Grimmspeed parts for the intake tract. Super nice construction,good fit. When you get with your tuner,look at your logs and notice how fast this thing drops intake temps when you get into boost. Worth every cent!
On a footnote--it came missing the lower splitter. Got in touch with Grimmspeed Cust Svc. Great people! Fixed me up quickly. Good products and great service!
