Installation was super simple and fit was perfect. I was extremely surprised with how much the stock injector tick was quieted in the cab.

the preciseness of this engineering is outstanding, fits perfectly, again Riffraff is ahead of the industry,

Excellent Product. I tried a cheap product before buying this. It didnt fit well and wouldnt last long term. I returned and purchased this and let me tell it, its a far superior product and actually seems to quiet the motor down a little. Great product!

Took some injector noise away Helped with hp oil surge

Decided to try out the oil crossover because it's simple and figured even if the results were minimal it'd only take a few minutes to put on. I was quite surprised at how much it actually quieted the truck down all around aside from also aiding the the oil system. I haven't had any leaks or issues so far after 4 months.

Fit was perfect. Good quality !!!

Fitment is great, excellent quality, third one I've purchased over the years really seams to help quiet down injectors, and pairs well with the frx, obviously I would buy again, a great addition to any 7.3

Fix’s perfect and you only need to take the intake bracket off to install and the truck will thank you for this upgrade.

good product and easy to install. had it in my truck in under 15minutes.
