Stainless Steel HPX 99-03

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.

    HPX line

    Fit perfect, shipped fast. Quieted down injectors slightly seems like it cranks slightly longer on startup but hard to really tell. I’m happy with purchase.

    Great product, it works!

    Posted by Dale Cadwallader on Nov 6th 2018

    I installed the SS HPX crossover tube, the High Flow Fuel CVD Fitting Set, and the RiffRraff Diesel High Flow Banjo Bolt set on my 1999.5 - 7.3L. The result was amazing! The 7.3 starts faster and smoother, even on cool mornings. The engine noise is much quieter from starting, idling and at highway speeds. Can't wait to spend more money and buy more performance parts from RiffRaff Diesel.

    Installed the HPx line on a 2000 F-250 Super Duty and I find the engine sounds more balanced and a bit quieter.

    Installed this a couple weeks ago in my 2000 7.3 and went in easy. Unfortunately, haven’t noticed any change in the sound like I was hoping for but I’d still do it just for the potential savings of my injectors.

    I am thoroughly impressed with the fit and quality of the part, helped my idle as stated, and seems to have better throttle response as well.

    Quiet Idle!

    Made my Early 99 7.3L nice and quiet at idle, even my wife noticed it. Better off idle response as well.
