Description

This upgrade is specifically engineered for the 2002-2007 Subaru WRX, 2004-2021 Subaru WRX STI, and the 2004-2008 Subaru Forester XT. It features an improved core design that excels at absorbing more heat, thereby mitigating heat soak more effectively than the stock unit. This is particularly beneficial during repeated hard pulls or when the engine is modified to increase boost pressure or throttle use, situations where the OEM intercooler's limitations become apparent. The installation is a direct bolt-in process, meaning no adapters, custom piping, or modifications are required; it utilizes the same connection points as the OEM intercooler. The kit includes the GrimmSpeed TMIC unit, couplers, mounting hardware, and installation instructions, ensuring a straightforward upgrade. The core itself is constructed with a bar-and-plate design and features a Thermal Dispersant Black coating for optimal performance and durability. GrimmSpeed, based in Portland, Oregon, has been a prominent developer of performance parts for Subaru platforms since 2003.
