This intake features a supernano web dry filter and massive horsepower and torque gains. During testing at Injen, this intake resulted in a +26 hp and +35.5 ft/lbs of torque gain. The enclosed airbox design offers a clean look and superior heat protection compared to traditional open element systems.
