Stainless Steel HPX - Ford 7.3L Powerstroke (94-97)
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 to flow to the opposite head, the issue of pressure spikes are less and allow for a smoother idle. We manufacture our own SS HPX lines right here in the USA unlike many companies today that outsource their product lines.

Easy

Bend was a little bit off
Very high quality piece. Spent a few hours trying to make it fit... Needed to be bent a little bit. Idle quality does seem a little bit smoother and so does the motor while I drove it around the block.

Should have come from the factory like this.
Very well made piece, I put it on a 1997 with 214,000 miles. Smoothed idle quality and did quiet the engine some at 75mph on the freeway. it did improve throttle response too.

HPX 94-97
Perfect fit and well-made top quality
-
awesome quality affordable upgrade
throttle response is noticeably better, idle is smoother/quieter. easy installation, will run rough until air is purged after installation. great upgrade and from forums that ive read riffraff makes the best quality crossover. other brands apparently have fitment and leaking issues.

Good deal
Haven't noticed and added horsepower but is worth the money for a quieter ride. Took almost all of the engine noise away.

Should have been!
97 7.3 I installed this item after baby swamps and ts6 chip. I noticed some better throttle response and some what less noisy I didn't discover the difference until I put my foot in it and well a smile came across my face well enough said buy your own and get your smile

Awesome
Definitely made the idle quiet down a little and smoothed it out as well. 10 out of 10 would tel everyone to get this!

Nailed it
Easy to install. Doesn't quiet the engine down completely but takes a good bit of the clattering ouout.
