Grimmspeed has released their awesome new cold air intake system for the 2015 and newer Subaru WRX platforms. Designed as a simple bolt-on modification, testing has resulted in considerable power gains for the turbocharged platform. Bringing out 32wtq and 21whp, these numbers are due in large part to the amount of work put into the research and development of this intake kit.
MAF diameter and placement, total bend angle, filter location, and heat shield design were the primary variables during the design phase. To minimize restriction, Grimmspeed made sure to keep the total bend angle in the intake tube as low as possible, but still raise the filter location away from the ground to protect it from the elements. When all the design was first tested, it showed the importance of utilizing the factory ram air scoop to feed the otherwise stagnant air in front of the fender. The engineers at Grimmspeed created a model of the intake and fender area in order to optimize each of these variables. The result is an intake with a total bend angle of 74 degrees, and a filter that is placed neatly within the fender, such that it offers protection from the elements without being unnecessarily exposed to the heat of the engine bay. The shape of the heat shield follows that of the factory air scoop, feeds the filter with fresh air evenly and promotes swirl which prevents pockets of motionless air on the cold side of the shield. When all is said and done, this intake has been optimized for the 2015 Subaru WRX and it shows though not only the performance output of the kit, but the additional minor details such as protected MAP sensor location, the sealed heat shield, and the exact fitment. So give this 2015+ WRX intake system a try, and see why the industry has been changed for the better by Grimmspeed!
