Agency Power AP-GH-110 Short Ram Intake Kit for 2008-14 Subaru WRX STi

Turbo cars need more air flow to make more power. Not only is air flow important, but how that air gets into your cars motor is an essential factor. With vehicle computers becoming more and more advanced, precision engineered products are necessary to optimize performance. Focused on quality, function, and style, Agency Power has developed this intake kit for the new 2008 and up Subaru WRX or STI.

This intake kit is sold as a short ram. The kit features a CNC aluminum MAF sensor mount on our intake tube with built in fins to keep air flow laminar. The intake kit includes a 5ply AP silicone coupler with clamps for easy install. To keep the cool air separated from the engine heat, Agency Power has developed this heat shield which mounts to factory chassis locations from the front crash beam to the fender. The high flow K&N cone air filter securely clamps in place to the short ram or cold air extension tube. The heat shields are powder coated in a textured black finish and the intake tubes are done in wrinkle red to match the STI intake manifolds.

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 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.

Agency Power highly recommends tuning your factory ECU when using any intake system larger than stock. This will allow for the highest power gain and prevent any operating issues.
