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.

Fit was great! Quieted down the engine and it feels loke it gets up and goes better. Faster turning over when starting. Love it.

5 Awesome cheap upgrade.

The fit is good. However I was under the impression that i had to use both of the third ports but i only had to use one of them. I DID NOT HAVE TO MOVE THE LINE ON THE DRIVERS SIDE. If I would have then the line would not work. My truck seems to run a little smoother, it seems to accelerate faster, and it turns over faster when you start it. Great investment. I am now waiting for my chip to come and see how it rins after that. I have a 97 powerstroke.

5 Great upgrade

What sold me on this upgrade was the great reviews that it is getting and the great quality products Riffraff sells. I put the stainless line on at the same time I put new Riffraff turbo boots on. Great installation and I can notice the difference in how my 96 idles and goes down the road.

Noticed immediately a quicker start and smoother idle quality. Had to tweak the tube a bit to get the threads to start... just be patient so you don't crossthread.

5 Works great

It quites the motor chatter right up and smooths the motor out. So no more rough idle. It just helps the injectors fire better.

4 Works Well on My 1997

The installation took a little bit more time than expected because I had to bend the tubing a little to get the HPX positioned right but otherwise the product works great. It smoothed out the idle on my truck and has quieted it down more than I expected.
