GrimmSpeed Thermal Dispersant Coated Top Mount Intercooler for Subaru WRX
The GrimmSpeed GRM090071 top mount intercooler combines a black thermal dispersant coating with a cross-flow bar-and-plate core, cast aluminum end tanks and TIG-welded construction.

Installation Notes
Follow GrimmSpeed's installation instructions, including splitter installation and factory mount reuse. Check coupler seating, clamp positioning and clearance before tightening, then inspect the charge-air system for leaks. Keep the unused 1/8 NPT port sealed. Discuss calibration requirements with your tuner for the vehicle's complete modification package; no specific horsepower gain, temperature reduction or knock-prevention guarantee is made.
