Cobb Stage 3 Power Package 2015-2020 STI

  • The Cobb Stage 3 Power Package is a simple bolt-on and tuning solution that will allow you to maximize the power output of your 2015-2020 Subaru STI! The heart of this package is the Accessport V3. With the increased airflow from a 3" Stainless Steel Turboback exhaust and SF Intake & Airbox combo, increasing the capability of the fuel system becomes pivotal in making more power reliably. The Cobb High Flow Fuel Pump, 1050cc Fuel Injectors, Fuel Rails, Fuel Rail Line Kit, Fuel Pressure Regulator for Fuel Rail Kit and Fuel Pressure Regulator Upgrade provide a substantial fuel system upgrade. Combine the airflow modifications and fuel system upgrades to maximize the power output with the factory turbocharger on your STI!
