Cummins Celect Injector Cummins Celect injectors are one of the most complex and advanced injectors in use today. The advanced technology in these injectors allows for increased power, lower emissions, and better engine responsiveness. Remanufacturing Cummins Celect injectors requires sophisticated equipment to recondition not found in many smaller fuel shops. Getting a CELECT injector to original performance specifications is 20 times more complicated than ordinary injectors. In other words, you can't just clean and rebox a CELECT injector and hope for the best. Mechanical injectors have one high pressure sealing joint while CELECT injectors have ten. In addition CELECT injectors have a much tougher cleanliness requirement and are much more difficult to assemble. Even if a rebuilder could assemble a CELECT injector, they would have no idea if it worked unless they obtained very specialized testing equipment. Plus there are critical hydraulic flow specifications that must be met in order for the engine to idle properly.  If you are replacing one or two injectors, it makes sense to replace all six. Replacing all six Celect Injectors can increase overall engine performance and help to avoid potential problems, especially with higher-mileage injectors. Doing so will give you the assurance of knowing that your injectors are operating at peak efficiency to deliver maximum performance and fuel economy. Overhauls, tune-ups, and overhead set service are great times to replace your injectors. Reconditioned Cummin CELECT Injectors: Meet Cummins specifications Utilize advanced materials Incorporate state-of-the-art Cummins design technology Are continually improved and built with the most up to date specs and materials
