These splitters have been in development for a long time. As the popularity of GrimmSpeed intercoolers has soared, there's been huge demand for splitters that boost the performance of our Top Mount Intercooler on the 08 - 14 STI platform. Some users have even achieved 600 - 700whp with them. These splitters seal perfectly with your GrimmSpeed TMIC, making the system work super - efficiently. With our dense cores, using a well - fitting splitter to force ambient air through the core is crucial, and these splitters make it easy. For STI owners with a GrimmSpeed TMIC, this is a must - have. Part #: 093114. Fitments: 08 - 14 Subaru STI (equipped with a GrimmSpeed TMIC). Quick Specs: Designed in CAD for a perfect fit with GrimmSpeed TMIC. Laser - cut 5052 aluminum for durability and light weight. Texture black powdercoat protects and looks great. Each kit includes a rubber bulb gasket for a perfect seal. 100% Made in the USA, right in Minnesota! Our cars generate a lot of heat, even with minor mods. When the turbo compresses intake air, it can reach over 400°F before entering the intercooler. That's why you've likely upgraded to a larger top mount. The intercooler uses ambient air from the hood and scoop to cool the compressed air. Without a proper splitter, you're not using your TMIC to its fullest. The GrimmSpeed splitters increase the opening size to fit your TMIC perfectly, potentially boosting internal core volume by 200%. You'll need that extra air to keep things cool. Design: Each splitter is designed to make the most of the air entering the scoop. The bottom is opened up to fit the GrimmSpeed TMIC better, and the vanes directing air to the intercooler are redesigned. Plus, each splitter has features for up to three intercooler water sprayers. They were designed in CAD 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 across the core.
Using your GrimmSpeed Top Mount Intercooler Splitter is easy. First, make sure your Subaru STI from 2008 - 2014 is equipped with a GrimmSpeed TMIC. Then, carefully install the splitter, using the included rubber bulb gasket to ensure a perfect seal. It's important to handle the splitter gently as it's made of laser - cut 5052 aluminum, which is durable but still needs care. When it comes to maintenance, you can clean the splitter with a mild soap and water solution. The texture black powdercoat helps protect it, but avoid using abrasive cleaners that could damage the finish. Check the gasket regularly for signs of wear and replace it if necessary. If you're using the intercooler water sprayers, make sure to keep them filled and check the connections to ensure proper operation. That's all there is to it! Enjoy the improved performance of your intercooler with this great splitter.
