The core of any top mount intercooler is the beating heart of the beast. The intercooler cools your hot charge air in two different ways. The first is by reducing temperature by transferring heat from your hot, compressed air by conduction through the fins of the intercooler. The second is from a small pressure drop due to the flow restriction in the fins. The idea when you’re selecting an intercooler is to find one that results in an overall increase in air density. Rather than designing the largest possible core, or the core with the highest possible fin density, we created a well-rounded unit that’s designed specifically for Subaru’s making up to 550whp. That said, this particular core flows over 1500CFM and will support up to 575whp before it’s likely that a FMIC might be better suited for your system.

Because of our dedication to providing an excellent, well-rounded product, you’ll find that with the proper y-pipe, the GrimmSpeed TMIC will install with ease. We designed the TMIC to work with your stock STI y-pipe. Don’t have one? No problem. We’ve also designed a cast aluminum y-pipe kit with a 4-piece 5-ply silicone couplers and t-bolt clamps for each and every connection (not included). Worried that your hood scoop splitter might not feed your GrimmSpeed TMIC with the air it needs to properly keep those outlet temps low? We thought you might, so we’ve also designed a lightweight splitter that’s optimized for our TMIC as well as whatever scoop you might have.
