Your OEM TMIC does just fine at stock boost under normal use, but as soon as you start putting some real heat into it with higher boost or harder use, it heat-soaks beyond recovery. GrimmSpeed has designed the ULTIMATE top mount intercooler for your performance oriented Subaru. Rather than designing the largest possible core, or the core with the highest possible fin density, GrimmSpeed created a well-rounded unit that's designed specifically for Subarus making up to 550whp. That said, this particular core flows over 1500CFM and will support up to 575WHP before it's likely that a FMIC might be better suited for your system. To achieve the quality, tight tolerances, pressure tightness and strength that you expect, permanent mold casting were used. Every end tank is cast from the same CNC machined mold, ensuring a dimensionally perfect castings with an amazing surface finish. After casting, every single mating surface is precision machined for a leak-free finish and unbeatable fitment. Finally every intercooler is hand TIGed then pressure tested to 50psi and thoroughly cleaned before it's sealed up and prepared for shipping.
The GrimmSpeed Intercooler kit also comes with a line of splitters that increases the size of the opening by 70% to your larger TMIC. The intercooler kit can increase your internal core volume by as much as 200% In addition, they have added provisions for up to three intercooler water sprayers to each splitter. You'll also find that the GrimmSpeed splitters are very lightweight. Instead of selecting a stiffer material, they've stiffened the design, which has allowed for use of 20 gauge 5052 aluminum to drop the weight of these splitters by 300% over the competition. Instead of welding the assemblies, flathead rivets were used. These offer the same mechanical joint but without stressing the material and because of that, you don't have to worry about breaking welds or your splitter cracking.
