Staged Power Packages

This is where to start your quest for additional power and response from the WRX. Included in the Stage 1 Kit is the highly regarded AccessPORT which is used to reprogram the factory engine computer, unlocking an additional 33 HP (power) and 43 lb-ft (torque) from a WRX and increases boost to approximately 14.7psi.

The Stage 2 Kit continues where the Stage 1 Kit leaves off. Included with Stage 2 is the AccessPORT, as well as the complete COBB Tuning Turbo Back Exhuast. Starting off the COBB Turbo Back system is the COBB Downpipe. The CAD designed bellmouth of the COBB downpipe makes sure the airflow is smooth and efficiant. The system finishes with the modest tip of the Cat Back section that sits completely flush with the bumper. With a subtle, but deep exhaust note, the COBB exhaust achieves the highest performance while still retaining a stock like appearance.

Requires no tools or mechanical knowledge to install. The AccessPORT does all the work of programming the factory ECU for you, just simply plug it into the factory service diagnosis port located below the steering wheel. Follow the on-screen instructions and within 10 minutes you'll be out driving, enjoying your new found performance.

In order to improve the already sizable performance of the WRX, our engineers have spent hundreds of hours researching the factory Engine Computer (ECU) programming and testing changes on our All-Wheel Drive chassis dynos.

Our goal is simple: to provide the optimal balance of performance, driveability, engine response, and reliability.

The AccessPORT, the core component in Stage 1, enables you with the freedom to continue the quest for additional performance if you desire in the future.  As other engine modifications are made, the AccessPORT will grow and adapt to your needs helping you extract the most from your WRX.

In addition to improved performance, the AccessPORT also has additional features allowing you to put the vehicle into special modes such as: Max Fuel Economy, Valet, or Security.
