Very good product. Made the idle of my 1997 ford much smoother. Fast shipping and good quality.

Smoothed out idle driving seems quieter installed that and ccv mod at same time.

Install was easy compared to some tasks just took paitence and a litte bit of planning to get it in but really simple to install.

Shipping was quick enough to beat me leaving for a trip was really happy about that and instruction were simple

Thanks For speedy deivery

2nd one I have bought they work great

Quieted down and smoothed out idle a slight amount. Was it like going from an IDI to a duramax? No. But it is quieter, and surprisingly I got a reduction in 3/4+ throttle smoke on 160 injectors.
Stainless hard line, much better than a hydraulic line. Solid construction, good quality.

Nice and smooth now!
The product is excellent, but the supplier really made it a one-stop shopping-ease pleasure!
Over the years, trying to find part numbers for these OBS F-350's is always the challenge, and fustrating. Then ordering parts from different suppliers as seems one guy specializes in just injectors, the other in OEM parts, etc.

RIFFRAFF RULES!
i was able to order everything needed for my injector and injector cup replacement job. Every OEM gasket, harness, oring, and HX line.

Shipping at the speed of sound!

The tool rental really is just the cherry on top!
Thanks Clay!

The line was very easy to install and does not leak. It is very well made and looks good under the hood. It did smooth out my idle and quiet down some clacking I could hear on the pass side rear cylinder. Thanks Clay!

Great product that made a huge difference in engine idle. After about 30 miles to get the air out the difference was obvious. Only trouble I had is that it took some bending and manipulating to get it on. Specs were off just enough that it was not a direct fit without issue.

I bought this kit and it was very easy to install I have noticed the truck does idle a little smoother.
Would recommend!
