CNC Fabrication HPX High Pressure Crossover Line for 99-03 7.3L Ford Powerstroke

Description Overview

No, you will not gain horsepower from adding an HPX to your Powerstroke. However, your truck will run smoother and your HPOP will last longer as a result of upgrading. As previously stated, this does not create more horsepower, nor is it intended to, but the majority of owners see a slight to significant decrease in engine idle noise. This is due to the helmholtz resonance effect that is created from the injectors firing so quickly, and the HPOP (High Pressure Oil Pump) cannot react quick enough to balance/absorb on its own from back pressure spikes within the system. So when the tiny spikes happen, the HPX line sends the pressure back and forth through the heads, instead of hammering on the pump itself.
