Ford Racing 15-17 5.0L / 5.2L Coyote High Performance Cam Phaser
Variable Cam Timing (VCT) phasers require proper oil pressure to function correctly. It is inherent that all cam phasers have a certain oil leak rate. These high-performance cam phasers have a much lower leak rate than stock, allowing better control of the phasers at higher engine speeds and loads. These cam phasers are oriented for racing applications.
