Why do I need a 3-port boost solenoid with an aftermarket downpipe or turbo?

The factory 2-port boost solenoid is designed for the stock turbo and exhaust system. When you upgrade to a higher-flowing downpipe or a larger turbo, the factory solenoid can't accurately control the increased airflow, leading to boost issues. A 3-port solenoid offers better resolution and control for these modified setups.

Is this a difficult part to install on my 2008-2014 Subaru Impreza WRX?

This boost control solenoid is designed as a direct replacement for the factory part. While it requires accessing the turbo and vacuum lines, it does not involve welding or extensive modifications, making it a manageable installation for those familiar with basic turbo system maintenance.

Can this part be shipped to California?

No, this Turbo XS boost control solenoid is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

If you're upgrading your 2008-2014 Subaru WRX with an aftermarket downpipe or a new turbocharger, you'll likely need to update the boost control solenoid. The factory 2-port solenoid just can't handle the demands of these performance parts, leading to inconsistent or uncontrolled boost levels. This 3-port boost control solenoid from TurboXS is designed specifically to replace that stock unit and give you the precise boost management your modified WRX needs.

Swapping to a 3-port solenoid is a common and necessary step when increasing airflow through your turbo system. It allows for more accurate communication between the ECU and the turbocharger, helping to maintain your target boost pressure more reliably. This well-built unit from TurboXS is a direct replacement for the factory part, making the installation straightforward for anyone comfortable working on their car's turbo system.

Keep in mind that this part is not CARB approved and cannot be shipped to California. It's a crucial component for getting the most out of your WRX's performance modifications.
