## Overview

The GrimmSpeed 57041 is a custom-machined, black anodized 3-port boost control solenoid adapter designed specifically for the 2015 Subaru WRX. It replaces the factory 2-port solenoid with a compact, plug-n-play solution that improves boost control by redirecting pressure back into the turbo inlet, enhancing tuning capabilities while maintaining factory sensor accuracy and reducing engine bay complexity.

## Description

An elegantly engineered solution. Custom Machined Adapter - Makes use of the factory inlet recirculation port, instead of blocking it off Black Anodized Finish - Protects the assembly from corrosion in an extremely demanding environment 1/4in Barbed Fittings - Matches the factory turbo and wastegate hose size 3-Port Solenoid - Proprietary internal modifications prepare the solenoid for extreme conditions below the vehicle Plug-n-Play Wiring Connector - Plugs directly into the factory wiring harness with no modification required Compact Design - No need to mount the solenoid elsewhere in the engine bay, increasing complexity and hose length If you've been in the Subaru game for long, you're probably well aware that a 3-port Boost Control Solenoid (BCS) is considered my most to be a 'must have' improvement before having your car tuned. GrimmSpeed has become the trusted brand in the BCS market, with tens of thousands of solenoids in operation today across the globe. The 2015 WRX offers a unique change of pace, as the factory 2-port solenoid is mounted directly to the plastic turbo inlet and interfaces with an o-ringed feature, rather than a vacuum hose. With expertise in designing machined parts and a tried and true boost control solenoid, we were excited to dig in and create a solution with an already proven pedigree of high performance and quality. The 3-Port Advantage The advantages of a 3-port boost control system vs. the factory 2-port system are readily apparent during the tuning process. The 3-port systems works by interrupting the boost signal traveling from the turbo to the wastegate. That boost is redirected back into the turbo inlet and re-ingested by the turbo using our machined adapter. This is important, as the factory Mass Airflow Sensor has already measured that air and is expecting that your motor will use it during combustion,
