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.

  1. Customer Service Excellent 4 Star Review

    Posted by on Nov 10th 2017

    First off, its a tight fit but does not require modification.

    2nd - I did not notice any noise reduction like bros talk about, though the exhaust on the truck has been modified.

    3rd.- I did not notice any performance gains, though the truck is more consistant at lower throttle.(less go pedal is needed).

    Lastly. The owner of the company answers the tech support phones here. And im not the first to make that statement, At the end of the day you cant beat that.

    Hope this helps gentleman. Be safe. Go mgtow.

    Made the engine run smoother and quieter. Unfortunately did not go in as smoothly as I would have expected. Got it in, but required some adjusting.

    Noticed significant noise reduction in the cab at freeway speeds. Better throttle response, quiet enough to hear the S&B intake whistle

  8. Bend was a little bit off 5 Star Review

    Posted by on Jun 28th 2017

    Very high quality piece. Spent a few hours trying to make it fit... Needed to be bent a little bit. Idle quality does seem a little bit smoother and so does the motor while I drove it around the block.

  9. Should have come from the factory like this. 5 Star Review

    Posted by on Jun 17th 2017

    Very well made piece, I put it on a 1997 with 214,000 miles. Smoothed idle quality and did quiet the engine some at 75mph on the freeway. it did improve throttle response too.
