GrimmSpeed Splitter for 2015-2021 Subaru STI

Are you tired of the OEM splitter restricting airflow to your top mount intercooler (TMIC)? Look no further than the GrimmSpeed Splitter, designed specifically for the 2015-2021 Subaru STI. This product is the result of extensive development driven by the rising popularity of GrimmSpeed's intercoolers. With many STI owners pushing their builds to impressive power levels of 600-700whp, a proper splitter is essential for maximizing performance.

Why You Need This Splitter

When it comes to cooling, every bit of airflow counts. As your turbo compresses intake air, temperatures can soar past 400°F before reaching the intercooler. If you're running a GrimmSpeed TMIC, this splitter is a must-have upgrade. It ensures a perfect seal with your intercooler, allowing ambient air to flow efficiently through the core. This design not only improves cooling performance but can also increase your internal core volume by up to 200%. With this splitter, you can ensure that your TMIC operates at its best, keeping those intake temperatures down.
