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 STI.

The Agency Power cold air intake 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.

With the Agency Power cold air intake on your 08-up EJ25 powered STI, you can expect peak power gains in the range of 10-15whp, with mid-range gains possibly even eclipsing 25whp.
