Injectors are then placed into an ultrasonic cleaner to remove all excess dirt and carbon. Once the cleaning is finished the injectors are then put into a machine and back flushed. The machine then preforms spray pattern, flow, leak, pulse width and vehicle simulation tests.
Worth every cent.
Replaced the 16YO factory units and the car is running as good as new - smooth idle and almost twice the power.
Installed in a 2003 VY V6 'S' Commodore.
