Since the WRX came to the states in the early 2000’s, it has become one of the top contenders in the tuner market. It’s turbocharged boxer engine combined with Subaru’s All-Wheel Drive makes it a force to be reckoned with on the street and the track. I personally have owned a WRX and have nothing but good things to say about that car. In 2015, Subaru released the new generation of WRX. The 2015 WRX ditched the previous EJ series engines for the new FA20 series engine, while the 2015 STI kept the tried and true EJ25 power plant.
The new FA20 engine has some flaws, one of them being the small intercooler sitting on top of the motor. One of the first mods that most owners buy, is a tune. Whether you choose to run an Accessport or a ProTune, you will most likely raise the boost on your WRX. The higher boost levels will increase the intake air temperature and the stock intercooler doesn’t have the capacity to cool down that charged air.
The new GrimmSpeed Top Mount Intercooler helps keep intake air temperatures down to avoid pre-detonation and loss of power. Testing also shows that the OEM Intercooler has a tendencies to fluctuate dramatically which can cause inconsistent power delivery. The GrimmSpeed Intercooler has proven to maintain a more steady outlet air temperature. This is a must have upgrade for those who are looking to take full advantage of their tuned cars.
