When it comes to selecting the right intercooler with maximum cooling and minimum restriction, then check out this GrimmSpeed unit. As air is pressurized by your turbo, it heats up, not because of the heat of the turbocharger, but because when they're 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.These units have been engineered to find that perfect balance with heat transfer and pressure drop. They began by laser scanning an OEM TMIC to plot the mounting points and space claim in CAD with pinpoint accuracy. At the same time, they
