For over a decade, GrimmSpeed intercoolers have been the standard for efficient design, low pressure drop, and unmatched heat rejection. Building on that legacy, this front mount intercooler kit was engineered from the ground up to deliver maximum cooling performance with no compromises.

Intercooler Core
The core is the heart of any FMIC system—get it right, and everything else falls into place. Using over a decade of intercooler R&D, GrimmSpeed designed a fully custom cross-flow core tailored specifically for EJ-powered STIs. Internal fin density, external fin geometry, and cast end tanks were optimized together to produce:
Extremely low pressure drop
Outstanding temperature reduction
Consistent performance under all driving conditions
Unlike many front-mount options, this kit retains factory coolant and washer reservoirs and avoids any major chassis modification. The included steel mounting brackets keep the intercooler firmly supported, even under aggressive track driving.
Light bumper trimming is required for the large core, and 2008–10 models will need a fog light delete.
Intercooler Piping
A high-performance core needs equally capable piping. GrimmSpeed’s piping system is constructed from:
.090”-wall, 2.5” 6061 aluminum
Large-radius CNC mandrel bends for smooth, unrestricted airflow
Bead-rolled ends to lock securely into the included 5-ply silicone couplers
Every pipe is finished in a durable powder coat that complements other GrimmSpeed components while also offering corrosion protection. Routing is engineered for OE fitment, allowing you to retain factory accessories with minimal adjustment.
First class service all the way very fast very efficient and extremely polite to deal with it on the phone
Jeremy,
Thank you for your 5 Star Review of the Grimmspeed FMIC Kit! The overall design of this front mount is spectacular! It has a massive core that still does not require you to make modifications to your bumper and provides tons of cooling!

2013 WXR front mount intercooler,....
I'd like to offer to make a dead how to install video for the year of my WRX,.... The YouTube video shows a slightly different bumper and vaguely mentions the other years that this kit is compatible with.... I think it's an AMAZING full kit,.... And with a few more how to install videos featuring all the different types of bumpers for WRXs available this kit can really be promoted well..
Hello,
Thank you for the detailed review! Great to hear you’re enjoying the intercooler kit, and we appreciate your feedback!
