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 in order 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 that we re-manufacture is flow tested on our in-house flow bench. Each injector has 4 tests that it must pass before being shipped out to you.
