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.

Excellent quality part
Excellent product, exact fit easy install. I’ve made my own (2 other 7.3s) using flexible hydraulic high pressure line but this product is superior in that it takes less room and is easy to install.

Very pleased
Install went very smoothly, did it in about 15 minutes after work. Off idle performance seems a little better. Most definitely a lot quieter which is the main reason I purchased this product. Idle is smoother and quieter and much less engine noise at cruising speeds. Highly recommended.

Easy instal, simple lil thing to do for your engine
It was easy to install, just had to bend it a lil bit for a better fit. I noticed a slight difference in the idle, it's just a lil bit quieter and smoother. Over all awesome product, made by awesome company. I definitely recommend it

Not as noticeable as some said
Installed couple weeks ago and it seemed to quiet noise a little bit not like some say. However that said for the money I think it’s a good purchase.
