LDCRE Turbocharger Boost Solenoid Valve for Ford 1.6L Turbo — CJ5Z-9K378-A/B Replacement with Pipe, Direct-Fit OEM-Style

LDCRE Turbocharger Boost Solenoid Valve (CJ5Z-9K378-A/B, 667-111) with pipe is a direct-fit replacement that restores stable turbo boost control for 1.6L turbo Ford models.

If your Ford Escape, Fusion, Fiesta, or Transit Connect (1.6L turbo) is showing irregular boost, hesitation, or inconsistent acceleration, a failing boost solenoid is a common culprit. This LDCRE unit replaces OEM part numbers CJ5Z-9K378-A, CJ5Z-9K378-B, and 667-111 and comes with the molded pipe for a straightforward swap. Built from durable ABS and metal components, it’s engineered to withstand repeated thermal cycles and maintain reliable operation in turbocharged applications.

How will this solenoid valve affect turbocharger performance?

The boost solenoid controls pressure signals to the turbo actuator or wastegate; a functional valve helps maintain consistent boost levels and smoother throttle response. Replacing a faulty unit prevents overboost events and reduces lag caused by control losses.

• Restores precise boost control to the turbocharger system
• Reduces hesitation and unstable acceleration
• Prevents pressure leaks that can trigger fault codes
• Includes the pipe for a sealed, OEM-style connection
