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.

Great Purchase
Noticed significant noise reduction in the cab at freeway speeds. Better throttle response, quiet enough to hear the S&B intake whistle

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.

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.
