Replace that undersized, plastic stock intercooler with a GrimmSpeed Top Mount Intercooler Kit, featuring cast aluminum end tanks, large bar and plate core and TIG welded construction. The factory FA20dit TMIC is well-suited for stock applications, but when boost levels are increased, the higher post-turbo air temps contribute to pre-detonation (or 'knock') and loss in power. The GrimmSpeed intercooler is designed to keep charge temps consistent during aggressive driving so that the rest of your parts can work to make power.

GS tested the OEM TMIC, GrimmSpeed TMIC and a leading competitor TMIC in a back to back to back comparison and used our multi-sensor data acquisition system to evaluate temperature deltas, intercooler efficiency, pressure drop and more. Below is a chart showing cooling efficiency between the three. To learn more and read the full testing write-up, please follow this link!
