COBB Tuning 3-Port Boost Controllers are a quick and easy way to help increase performance. A simple and compact solution to increase and stabilize boost on your Subaru Impreza. They use a 1/8 inch low profile barb fitting that is nickel coated for corrosion resistance. Viton spools and seals are used for both longevity and for proper seals as well. Each boost controller kit is specific for its application and installs easily on a stock location. Most kits also include instructions for internal and external wastegate setups. With a operating rating of 120 PSI, these kits are built for any situation!

ECU TUNING WITH A COBB ACCESSPORT IS REQUIRED FOR THIS PRODUCT.

Key Features:

• Spool faster and smooth out fluctuations.
• Plug and play with tuning (OEM connector plugs in).
• Comes with a custom aluminum mounting bracket, stainless steel hardware, the necessary boost-line to complete all connections, and zip ties to route the boost line neatly through the engine bay.
• Rated up to 120 PSI.
• Nickle plated fittings will not break like cheaper plastic ones.
• Simple install and easy to tune.

Tuning Note: As with any boost controller, if used to raise boost significantly (more than 2-3 PSI) we strongly recommend a full ECU re-tune for best performance and engine life. For this product, a COBB AccessPORT is REQUIRED to control and adjust boost setting on the controller.
