Injen's Evolution air intake system for the 2015+ Subaru WRX STI features a super-nano 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.
The Injen Evolution intake replaces the factory airbox and intake tube and also includes a custom air scoop. The existing MAF sensor and hoses connect to it to ensure a proper fit with no check engine lights.
