Restore factory-correct turbo performance with the Genuine OEM Ford Turbo Wastegate Boost Solenoid & Vacuum Harness Kit, part numbers F81Z-6C673-AA (solenoid) and MC3Z-9E498-A (vacuum line/harness). Designed specifically for the 7.3L Powerstroke, this complete OEM kit ensures accurate wastegate control, stable boost pressure, and reliable turbocharger operation under all driving conditions.
The wastegate solenoid precisely modulates vacuum to the turbo’s wastegate actuator, preventing underboost, overboost, turbo lag, or erratic boost spikes. Paired with the updated OEM vacuum harness, this kit eliminates common issues caused by cracked lines, leaks, weak solenoids, or inconsistent pressure signals.
Built to Ford’s exacting standards, both components feature heat-resistant materials, engine-bay-proof construction, and a perfect direct-fit design—no modifications needed. Ideal for high-mileage 7.3L trucks, performance builds, or preventative maintenance to keep your turbo system operating at peak efficiency.
