Cobb 08-12 Subaru WRX / 08-12 STI Hatch / 11-12 STI Sedan 3-Port Boost Control Solenoid

This is a COBB 3-Port Boost Control Solenoid, designed to fit your 2008-2014 Subaru Impreza, including WRX and STI models. If you're looking to fine-tune your turbocharger's performance, this solenoid plays a key role in managing how much boost your turbo creates. It's a direct replacement for the factory unit, but with a design that allows for more precise control over boost levels, especially when you're running an aftermarket tune.

The 3-port design offers a more responsive and accurate way to regulate boost pressure compared to the stock 2-port solenoid. This improved control is important for maintaining consistent boost targets, preventing over-boost situations, and ensuring your engine operates safely and efficiently under load. It's a well-built component that integrates seamlessly with your vehicle's existing turbo system, making it a popular choice for Subaru owners looking to optimize their engine's power delivery.

When installing this, you'll want to ensure you have a proper ECU tune to take full advantage of its capabilities. It's designed to work with aftermarket tuning solutions that can properly command the solenoid for optimal performance. Make sure to consult your tuner or the COBB installation guide for specific recommendations related to your vehicle's setup.
