This CAI was tested on a Mustang all wheel drive dyno, the Agency Power intake kit was installed on a 2008 Subaru WRX Sedan. The kit gained approximately 10 horsepower and 10 ft/lbs of torque. At the peak horsepower point of 5000 rpm’s, the intake kit made almost 20 wheel horsepower. The intake kit fits all 2008 and up Subaru WRX and STI vehicles.
Because Agency Power includes a 3" tube with this intake, ecu tuning is required for best results.
