Stainless Steel HPX for Ford 7.3L 99-03

The Stainless Steel High Pressure Crossover is meant to allow excess oil pressure to flow between both heads allowing for better supply to the injectors. By allowing the oil the flow to the opposite head, the issue of pressure spikes are less.

    Follow the instructions and torque the fittings so you don’t over compress the o rings. May be my imagination but I do think the idle is a little smoother.

    This is very well made(like everything riff raff has). Install was a breeze and made a noticable difference to me in the smoothness of the engine.
