Is your OEM splitter making your TMIC choke? Yeah, we’ve all been there. You pop the hood, and that bulky factory splitter just stares back at you, blocking all that sweet ambient air your top mount intercooler (TMIC) craves. If you’ve upgraded to an STI scoop, you know you’re missing out on some serious airflow. Or maybe you’ve already got an STI splitter but want to squeeze every last bit of performance from your setup. Whatever the case, GrimmSpeed has got your back with their TMIC Splitter lineup. And trust me, it’s worth your attention.

Let’s get real for a second. When you start modifying your ride, heat becomes a serious issue. Your turbo is working hard, compressing that intake air, and it’s not uncommon to see temperatures soaring over 400°F before it even hits your intercooler. If you’ve upgraded to a larger TMIC, you’re on the right track, but if you’re still rocking that OEM WRX splitter, you’re seriously limiting your gains. GrimmSpeed’s splitters boost the opening size by a whopping 70%, which means your larger TMIC can actually breathe and cool that hot air effectively. Some of these TMICs can increase internal core volume by up to 200%, and you’ll need every bit of that extra airflow to keep things cool under the hood.

• 70% Increase in Flow Capacity: This isn’t just a number; it massively improves your TMIC’s ability to shed heat.
• Maximized TMIC Efficiency: Say goodbye to high outlet temps and hello to more aggressive tuning potential.
• Designed for Even Flow Distribution: This ensures the entire core gets to do its job cooling that hot charge air.
• CAD Design and Simulation: You can count on it fitting right and functioning as it should.
• CNC Laser Cut 5052 Aluminum: Built to withstand heat and vibration without fatigue.
• Durable DuPont Black Powdercoat: Gives it a sleek OEM finish while protecting it from the elements.
• Custom EPDM Rubber Gasket: This seal is built to last, keeping everything snug and tight.
• 3x Intercooler Sprayer Ports: You can use your STI TMIC sprayer or add one if that’s your vibe.

• Subaru WRX 2002-2003 with USDM WRX Scoop

• This fits WRX models equipped with either a GrimmSpeed or OEM STI TMIC.

So, if you’re ready to stop choking your TMIC and start getting the most out of your setup, this splitter is a solid investment. It’s all about keeping that air flowing and your temperatures down, and GrimmSpeed has nailed it with this design.
