Injen Evolution Cold Air Intake
Fits: 15-17 STI

Fitment

  • 2015-2017 Subaru | WRX STI

Description

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.
