Hey there, fellow gearheads! If you’ve ever popped the hood on your WRX and felt a twinge of disappointment thanks to that stock splitter blocking airflow to your top mount intercooler (TMIC), you’re not alone. That OEM splitter can really cramp your style, especially if you’ve upgraded to something like an STI scoop. You want to make sure that intercooler gets all the cool air it can, right? Well, the folks at GrimmSpeed have put their heads together and come up with a solution that’s worth your attention—five solutions, to be exact. Let’s dive into the GrimmSpeed TMIC Splitter lineup.

When you start messing around with mods, your car can generate some serious heat. I mean, we’re talking about intake air temperatures that can soar over 400°F as your turbo works its magic. If you’ve already invested in a larger TMIC, that’s great, but if you’re still rocking the factory splitter, you’re really not maximizing its potential. The GrimmSpeed splitters bump up the airflow opening by a whopping 70%, which is a game changer for those bigger intercoolers. Some of those can boost internal core volume by up to 200%, and trust me, you’ll want all that extra ambient air to keep your temps in check.

• 70% Increase in Flow Capacity: This isn’t just a number—it seriously amps up your TMIC’s ability to cool down that hot air.
• Maximized Efficiency: Lower outlet temps mean you can push your tuning a bit harder without worrying about heat soak.
• Even Flow Distribution: The design ensures that the entire core gets to do its job cooling the charge air.
• Precision Engineering: CAD design and simulation guarantee that what you get fits like a glove and performs as it should.
• Built to Last: Made from CNC laser-cut 5052 aluminum, these splitters resist fatigue from heat and vibrations.
• Sleek Finish: The durable DuPont black powder coat gives it an OEM-like finish while protecting it from the elements.
• Custom Gasket: The EPDM rubber gasket ensures a solid seal and longevity, so you won’t be replacing it anytime soon.
• Sprayer Ports: Comes with three intercooler sprayer ports, so feel free to use your STI TMIC sprayer or add one if you’re feeling fancy.

• Subaru WRX 2002-2003 with JDM STI Scoop
