Cobb Tuning 3 Port Boost Solenoid - Mazda 6 MPS / Mazda 3 MPS BK/BL 06-13

Cobb Tuning's 3 Port Boost Control Solenoid is a precision upgrade for turbocharged Mazda applications, delivering stable and repeatable boost control that the factory system simply can't match. Whether you're running stock boost or pushing hard with a big-power build, the Cobb BCS gives you the consistency and accuracy needed for reliable tuning results.

This listing covers the Mazda 3 MPS BK and Mazda 3 MPS BL (2006–2013), as well as the Mazda 6 MPS. The unit mounts in the factory location and connects directly to the stock wiring harness. Optional 6.35mm (1/4 in) nickel plated barb fittings are available separately if required.

Important: Custom tuning is required to make use of this product. This is not a plug-and-play performance upgrade without appropriate ECU tuning.
