GrimmSpeed Top Mount Intercooler Black - Subaru WRX 2002-2007 / STI 2004+ / Forester XT 2004-2008

So, you probably already know that you want an intercooler with maximum cooling and minimum restriction, but when it comes to selecting the right one for the job, we think it’s important to understand why. As air is pressurized by your turbo, it heats up, not because of the heat of the turbocharger, but because of it being compressed, the atoms in the air are forced closer together and as a result, move faster and have more energy. That energy manifests itself as heat. The more heat we can remove from the system, the denser the air becomes and that’s what helps eliminate pre-detonation, or ‘knock’, allowing for increased output from your system. 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.
