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
Great product! good quality, fast shipping, perfect fit. No complaints. Made my truck a lot quieter at idle and maybe even a little going down the road. When truck is cold started now it doesnt have any injector noise almost as if it was already warm. Thanks for another quality product.

Easy install / great fit
I’ve installed this onto a f-550 7.3L mechanics truck. I’m not sure if it has made the engine run any quieter or not, but I have this crossover on my other f-350 7.3L work truck & thought I would give it a try. Install was pretty simple. Only took 20 or 30 minutes. Good fit.

Best Add-on for Price
First got this for my personal 7.3 and noticed a little difference but I bet if I hooked up a scan tool you could see a huge difference with icp signals. Liked it so much I installed it on a customers truck after a new set of injectors.

Supper easy for me to install. Great product. My 7.3l excursion is not as loud now and smoother. I plan on purchasing more products from riffraff.

HPX
Amazed! A simple, well made product that not only dramatically silenced my 2001 f250 but also eliminated injector chatter under hard acceleration. A Riffraf must!

Great Deal Superior Product
The item was as advertised, the how to video put out was spot on. Installation was very easy, the part has been in for almost a month now with no leaking issues.

Easy install and it looks good. Not sure about the affects of the crossover but it makes sense to me.

HP Oil Crossover Line
This Crossover Line was extremely easy to install without needing to remove the turbo. No leaks and smoother idle.
