The C.A.R.B. certified COBB Tuning SF Intake for the EVO X utilizes our own unique design that provides smooth air flow to the turbocharger. When installed on a stock EVO X, our SF Intake system frees up an additional 21 HP and 24 lb-ft of torque to the wheels. Expect even larger gains when running higher than stock boost levels. Simple to install, this is great first step in your quest for more performance.
