COBB Tuning 3 Port Boost Control Solenoid Subaru WRX (VA) / Levorg (VM)

COBB Tuning 3 Port Boost Control Solenoid - Subaru WRX (VA) / Levorg (VM)

COBB Tuning has built a strong reputation for precision boost management hardware, and the 3 Port Boost Control Solenoid is one of their most practical upgrades for turbocharged Subarus. Designed to eliminate the inconsistency of the factory boost control system, it delivers stable, repeatable boost across the rev range — whether you're running stock boost or pushing hard with a big power build. Engineered for direct plug-in installation and long service life, this BCS is purpose built for Subaru WRX and Levorg applications.

This listing covers the Subaru WRX VA (2015–2021) and Subaru Levorg VM (2014–2021).

Important: Custom ECU tuning is required to get the most from this solenoid. It is not a plug-and-play performance upgrade without appropriate tuning support.
