The NMRA Technical Department and Ford Performance engineers have researched and discussed several areas of concern with the Gen II Coyote Stock engines with racers and engine builders. The extreme conditions of the category can result in issues that might affect power and/or performance.
Due to these findings, the NMRA Tech Department will allow the following components to be replaced under NMRA Tech supervision. This optional upgrade is limited to the following two parts only:
- Gen II Cam Phaser's may be replaced with PART # -M-6004-A50R 2015-2017 5.0L/5.2L Coyote High Performance Cam Phaser
- Gen II VCT Solenoids may be replaced with PART # -M-6297-M50A - 5.0L High Strength VCT Solenoids
