This is our smallest upgrade. We modify your injector to flow 20cc over stock. You will see a gain in fuel economy and low end torque. With these injectors you will have to run custom tuning to get them to idle properly and to maximize the potential of the injectors. Blue spring and upgraded banjo bolts are recommended.We re-manufacture all internal mating surfaces, inspect all pieces of the injector, replace defective parts,and test each solenoid. Every o-ring in and on the injector is replaced. Every injector we re-manufacture is flow tested on our in-house flow bench. Each injector has 4 tests that it has to pass before being shipped out to you.

FEATURES: These injectors will require aftermarket lift pump and regulated return to ensure the proper fuel is supplied to the injectors.Every o-ring in and on the injector is replaced.Each injector has 4 tests that it has to pass before being shipped out to you.
