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.
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 ca
n work to make power.

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

The GrimmSpeed engineering team has a history of developing the highest performing
Top Mount Intercoolers available and the 2015+ WRX fitment will be 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.

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. To learn more and read the full testing
