Product worked great did exactly what it was supposed to do my only complaint is that the packaging could be better mine was bent in shopping

Fits great, very good upgrade.

Quality fit and finish and sure calmed down the engine idle a lot.

I found that after installation and the initial run in time to remove any air in the system, that my old 7.3 would run smoother and pull more even and also idle more even. some of the diesel knock at idle had almost disappeared. only takes about 50 psi, different between injectors. the way it runs now, I'm sure my 7.3 will last longer. Just can't figure why it wasn't it installed from factory.

Extremely nice fit and finish. No worries on rubber/braided hoses rubbing through, stainless is the way to go! Was on and back running within 10 minutes, very noticeable difference with no shudders or spikes returning to idle any more.

High quality and perfect fit. The truck now idles smooth and no longer has a "lope" when starting on cold mornings. Acceleration and deceleration are now smoother without the drop in RPMs when coming to a stop. This is an inexpensive upgrade to a smoother running struck.

I have an intercooler and E-fuel upgrade, there are no clearance issues with the HPX.

First off fantastic quality product, I will say getting it on is a little tricky because of the oil line in the way, a small pry bar and you’re good to go. Smoothed out my idle a ton. Fantastic product.

My 95 obs 7.3 has a lot of miles and was idling really rough on cold starts. Installed the hpx line and some stiction eliminator and she purrs like a kitten

Put it on my 97 has 180/30 and an adrenaline hpop thing idles really smooth now definitely be getting two more for my other 7.3s
