Seven original agency injectors. The rubber seals have been changed and they have been manually cleaned, not with a machine. Because the machine widens the openings and causes fuel consumption. The injectors have run 50,000 km, almost new, and have a one-week warranty after installation. Install them and trust in God, I am responsible. Tested and inspected. There are two rubber seals included as spares. Of course, the rubber seals are original Motorcraft, not aftermarket.
