Description
Description
CNC Fabrication HPX High Pressure Oil Crossover Line – 7.3L Powerstroke
The CNC Fabrication HPX High Pressure Crossover Line is designed to improve high-pressure oil system stability on the 7.3L Powerstroke. While it does not create additional horsepower, many owners experience a noticeable reduction in engine idle noise and smoother operation.
This improvement comes from reducing pressure spikes caused by injector firing speed. The HPX line allows oil pressure to balance between both cylinder heads instead of hammering the HPOP, minimizing the Helmholtz resonance effect and smoothing system response.
🇺🇸 Made in the USA
