Mitsubishi Ralliart Boost Control Solenoid - COBB - 3-Port - 09–12. A proven electronic solenoid that delivers precise, reliable boost control for the 2009–2012 Lancer Ralliart.

COBB’s 3-port design offers finer wastegate management than the factory unit, helping achieve stable target boost and consistent performance after proper calibration. Built for under-hood durability, it integrates cleanly with the factory turbo system and supports both stock and upgraded setups when tuned accordingly.
