I noticed the top end of my stock 2002 f350 7.3l was more smooth and quiet than my non-hpXover.

Riffraff quality product that worked well with the EBPV pedestal delete. Bends and routing worked great and smoothed out the idle of my truck.

The HPX really seems to have smoothed out the idle of the truck and runs quieter as well. I would recommend this product to any 7.3 owner.

Excellent Design, great materials, and very well fabricated. I'm a working Licensed Mechanical Engineer, and it was a joy to see it, install it, and find it helps as much as people say. USA, as it used to be. My Truck is smoother, quieter, and seems to just run better overall. 2000 F250-7.3L Lariatt, crew cab, long bed that has had pretty good maintenance and upkeep, 179,600 miles.
Goes together exactly as stated. Very easy to install. Instructions are dead on. Photos very helpful. Once the two separate nipples are installed and torqued as noted, I Fit each receptacle nut loosely and threaded them down evenly on the nipples. Then just a tug of the open end wrench on each and it was done. No oil weeps, just works as advertised. GREAT PEOPLE and Products.

Very high quality piece, the bends were perfect and the line basically fell into place. Couldn't have asked for more especially at such a reasonable price.

Had a stainless braided line for about 2 months, then it started weeping around the crimps. Decided to try these guys and man what a difference. Been running it for close to 9 months now, no leaks no weeps. Don't waste your time on braided lines like I did.

I installed the oil crossover and started the truck up. It was much smoother at idle and a quieter running motor overall. I would install this part on all 7.3l motors.

Does exactly what it says. My truck is quiter and feels more smooth in the acceleration. Also, from design to manufacturing to the end user, I was thoroughly impressed. Materials are high quality. Service is awesome. Even the packaging was thought through. I have and would recommend this to everyone who has a 7.3

Installed and the O-rings didn't hold very long under pressure, and blew out. Did not over tighten. Ended up using O-rings from plugs and is holding fine. Seems to run smoother and a little quieter. Fit is perfect, no hassling to get it to fit right. Thanks
