Important Installation Notes: Professional installation and injector calibration by a shop experienced with oversized injectors is strongly recommended. When removing nozzles, be careful not to lose the small steel disks located inside each injector. Always label each injector to ensure they return to their original cylinder position, as the 6.7L ECU learns individual injector characteristics and may reject incorrectly positioned injectors.
