Stainless Steel HPX - Ford 7.3L Powerstroke (94-97)
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 to flow to the opposite head, the issue of pressure spikes are less and allow for a smoother idle. We manufacture our own SS HPX lines right here in the USA unlike many companies today that outsource their product lines.

7.3 crossover pipe
Great product easy install. Truck is easier to start. Sounds much quieter. Runs smother. Well.worth the money.

HPX
Great product. As others stated, bend is not perfect need to adjust a bit to get threads started. No oil leaks and looks good. Combined with a new ICP sensor and back pressure sensor 7.3 never ran better.

Easy...
As with all RiffRaff designed / engineered products and tools, this one is first rate, top quality. Most likely the easiest install of any product I have purchased for my truck. My oil supply line was in the way with a clamp which required 'turning the clamp around', but other than that, it literally took no more than 10 minutes. Truck seems quieter (smoother?) at highway speed, but other than that no noticeable changes. (truck was always an easy/quick starter).
Thank you! -
Good Investment
Excellent product, easy installation, great price. Crossover did quiet down motor a little. Starting was definitely quicker. Thanks RiffRaff

HPX for OBS Powerstroke
Great product. Easy install too! My truck is much smoother at idle and start ups now. And even smother acceleration. Thanks!

HPX
This product is well built, the only reason I gave it 4 instead of 5 stars is that I had to bend it to get it to line up with the JIC fittings. I have not noticed much difference in the way the truck runs or sounds, but I honestly haven't driven it much since. The idea of equalizing oil rail pressure makes a lot of sense, so I am happy with the part even if I don't notice a difference.

Great Quality
Glad I finally did this mod. Noticed a much better idle, and I can see it has smoothed out my ICP graph on my autoenginuity scanner as well.

Good looking/ working product.
Just installed the ss hpx line looks good works good no leaks. The only bad thing was the bend was not quite right took some words and a little bending to get the threads started. Other than that it's a good product so far.
