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 comes with adapters, ready to install.

    Well made, instructions easy to follow, easy installation. Only been in a couple days can't tell if it's smoother and more quite yet ?? All products have I've ever ordered from riffraff have exceeded my expectations and shipping on time or sooner.

    Worked great, had to bend a little

    HPX worked great but I have a 2001 E-350 7.3L van and hand to put a little bend on the tube for it to fit between the turbo and the intake boots.

    Great Product

    This was an easy install and smoothed out the idle completely. Only the highest quality components went into this. Fit and form are perfect. Clay and RiffRaff are top notch!

    Excellent product

    Very easy to install, did this with the Fuel Rail crossover as well. Could definitely tell a difference in before and after on quietness and much smoother idle. Really a great addition to your 7.3 to balance the oil between the 2 heads and smooth things out.

    Very easy to install

    I've been trying to get my 10 y/o son out of the house this Summer and off of his computer. So I've been using that as an excuse to order a lot of parts here and use them to teach him how to work on vehicles rather than how to build stuff in minecraft. I have to say, this was such an easy install my boy almost did the whole thing himself.
