The Enginetech ECP8422 is a variable valve timing (VVT) cam sprocket/phaser assembly. Fits 2004-2014 Ford/Lincoln/Mercury 4.6L/5.4L applications.
Important Notes
- Aftermarket-design phaser: this universal unit replaces both the OE left-bank and right-bank sprockets. Two (2) units are required per engine. Verify that the application accepts the aftermarket-type sprocket before ordering.
- Service recommendation: replace the VVT phaser as part of any major timing chain service. A worn or sticking phaser causes cam timing codes (P0011, P0014, P0016, P0017), rough idle, and loss of power at specific RPM bands.
- Always verify the cam position (intake vs exhaust), engine bank (left vs right), and specific engine application against the phaser spec before ordering. Phasers are not interchangeable between cam positions or between engine families, even when displacement matches.

Enginetech Variable Valve Timing (VVT) Cam Sprockets are precision-engineered cam phaser assemblies that replace the OE VVT sprocket at the front of the camshaft. The phaser integrates with the engine oil control solenoid to vary intake or exhaust cam timing on demand, tuning power delivery, emissions, and fuel economy across the RPM range. VVT phasers are a routine wear item and should be replaced as part of any major timing chain service; a worn or sticking phaser causes cam timing codes (P0011, P0014, P0016, P0017), rough idle, and loss of power. Always verify the camshaft position (intake vs exhaust), engine bank (left vs right), and specific engine application against the sprocket spec before ordering - phasers are not interchangeable between cam positions or between engine families.
