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. Easy instal, simple lil thing to do for your engine 4 Star Review

    Posted by on Jan 10th 2018

    It was easy to install, just had to bend it a lil bit for a better fit. I noticed a slight difference in the idle, it's just a lil bit quieter and smoother. Over all awesome product, made by awesome company. I definitely recommend it

  2. Not as noticeable as some said 3 Star Review

    Posted by on Dec 17th 2017

    Installed couple weeks ago and it seemed to quiet noise a little bit not like some say. However that said for the money I think it’s a good purchase.

  5. Easiest and cheapest mod 5 Star Review

    Posted by on Nov 27th 2017

    Excellent product installed it on my lunch break which is only half an hour and I already ate my lunch. Instantly changed my idol to very smooth and a little quicker for a response at idle, a slight difference in throttle response while driving which is great. The cheapest and best mod you can do to any 7.3.

    This tube made a serious difference in my idle and overall performance.. thanks again riffraff

  8. 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.
