Upgrade your 2015 - 2021 Subaru STI with a GrimmSpeed Top Mount Intercooler Splitter. This splitter is a must - have for STI owners using a GrimmSpeed TMIC, though the intercooler itself is not included. As GrimmSpeed intercoolers have become extremely popular, we've seen huge demand for splitters that boost the performance of our Top Mount Intercooler on the 2015+ STI. Some users even achieve 600 - 700whp with them! These splitters seal perfectly with your GrimmSpeed TMIC, ensuring top - notch efficiency. Our dense cores make it crucial to force ambient air through with a well - fitting splitter, and these splitters do just that easily. Quick Specs: CAD - designed for a perfect fit with GrimmSpeed TMIC; laser - cut 5052 aluminum for durability and lightness; texture black powdercoat for protection and a sleek look; a rubber bulb gasket in each kit for a tight seal; and 100% made in the USA, right in Minnesota! Modified cars generate a lot of heat. When the turbo compresses intake air, it can reach over 400°F before entering the intercooler. That's why you might have upgraded to a larger top mount. But without a proper splitter, you're not getting the most from your TMIC. The GrimmSpeed splitters increase the opening size to fit your TMIC, potentially boosting internal core volume by 200%. You'll need that extra ambient air to keep things cool. Design - wise, these splitters are made to make the most of the air entering the scoop. We've opened the bottom for a better fit and redesigned the air - directing vanes. Plus, each splitter can support up to three intercooler water sprayers. They were CAD - designed and flow - tested before production. Our engineers used 3D scanned CAD data from the vehicle and TMIC development to ensure a good fit and even air distribution. The GrimmSpeed splitters are also lightweight. We tested other splitters that use stainless steel for stiffness, but we stiffened the design instead. This allows us to use 20 - gauge 5052 aluminum, making our splitters 300% lighter than the competition. We use rivets instead of welding to avoid material stress, so you don't have to worry about welds breaking or the splitter cracking. Each splitter comes with an EPDM rubber bulb gasket that's easy to install and can withstand the tough under - hood environment.
Using the GrimmSpeed Top Mount Intercooler Splitter is easy. First, make sure your Subaru STI is from 2015 to 2021 and is equipped with a GrimmSpeed TMIC. Then, take out the splitter from the package along with the included EPDM rubber bulb gasket. Carefully install the gasket around the appropriate area of the splitter. Next, align the splitter with your GrimmSpeed TMIC and secure it in place. When using your car, keep in mind that this splitter helps force ambient air through the intercooler core. This is especially important when your car is generating a lot of heat, like during high - performance driving. For maintenance, regularly check the splitter and the gasket for any signs of damage or wear. If you notice any issues with the fit or if the gasket is no longer sealing properly, it might be time to replace the parts. Since the splitter is made of 20 - gauge 5052 aluminum with a texture black powdercoat, it's fairly durable. But try to avoid hitting it against hard objects to prevent dents or scratches. Also, keep the under - hood area clean to ensure the splitter functions at its best.
