If you're serious about getting the most out of your turbocharged Subaru, you’ve probably heard about GrimmSpeed Intercoolers. They’ve been setting the bar for high-performance heat exchangers for a while now, and for good reason. Their latest offering, the GrimmSpeed 2015-21 STI Front Mount Intercooler Kit, is what a lot of us have been waiting for.

At the heart of any intercooler is its core, and GrimmSpeed really nailed it with this one. They’ve taken over a decade of experience and crafted a custom design that balances low pressure drop with high heat rejection. This is crucial for keeping your engine safe and performing at its best. The core measures in at a solid 27"x11"x4", constructed with a durable bar and plate design that’s been optimized for maximum airflow. You get phenomenal cooling without the risk of ending up with an expensive piece of junk.

These guys didn’t stop at just the core, though. The cast aluminum end tanks are designed for equal flow distribution, which means you won’t have to deal with any annoying pressure drop. Plus, the robust steel mounting brackets keep everything securely in place, even if you’re pushing your STI to the limit on the track. I’ve seen too many kits that require you to cut up your bumper or mess with the washer tank just to fit the piping, but GrimmSpeed has thought this through. You’ll only need to remove a couple of tiny ribs from the OEM undertray and make a few cuts to the splash guard. That’s it.

Speaking of piping, the kit includes thick, .090" wall, 2.5" inside diameter aluminum tubing that’s been CNC mandrel bent for perfect fitment and flow. They’ve bead-rolled the ends and paired them with 5-ply silicone couplers, so you won’t have to worry about blow-offs, even under high boost. And let’s not forget the gorgeous red or black wrinkle powdercoat finish—looks fantastic and matches up nicely with your other GrimmSpeed parts.
