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.

    This is the easiest modification I have done. Engine is noticeably quieter. O-ring on one side ripped, but customer service/technical advisor cheerfully gave me the spec. to get replacement locally. But this mod is so easy, that replacing the o-ring was a snap.

    You can install this without removing anything on the engine. The only thing I recommend is to be careful when tightening the banjo bolts into the head. Awesome product my engine is significantly quieter and running more smooth.

    Installed this in the dark with a headlamp on my 2000 F250 without removing anything from the motor. I noticed more stable idle RPMS immediately after installation and overall truck seems to be running more fluid, it doesn't feel like its chugging along as much. Well worth the money in my opinion, and huge thumbs up for Riff Raff on quick shipping and love the stickers and pens!
