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.

Perfect fit, super easy install, excellent performance!
Bought my 99' F350 from the original owner with 285k miles on the clock. In the last few years the previous owner did all the big repairs such as injectors and HPOP just to name a couple. I'm looking to make this old girl last as long as possible with "reliability upgrades" and maybe gain a little performance. This checks one of a long list of boxes. Great product!

I would highly recommend this product. Easy to install. I noticed a significant noise reduction from injectors on startup and at highway speed. Also noticed an increase in throttle response. Highly recommend this product. 1999 to 2003 7.3 powerstroke

HPX High Pressure Oil Crossover
Great little addition for the money. Super easy instal, no leaks right off the bat. I've only had it in for a few days but am starting to see a noticeable difference. The truck seems to warm up faster, turns over quicker on cold days, and idles a lot smoother. The truck sounds different at idle for sure.
