Injen has recently released their Evolution Air Intake System for the 2015+ Subaru WRX STI with the 2.5L engine. 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.
This Injen Evolution Air Intake System will replace the factory airbox and intake tube and also includes an air scoop. The existing MAF sensor and hoses will connect to it to ensure a proper fit with no check engine lights.
Application: 2015+ Subaru WRX STI (2.5L)
