    Great bump in power

    Posted by Chris on Mar 22nd 2017

    I received the injectors fast like any product I have purchased from clay. After removing the old injectors and installing these it makes my truck really wake up. It's just the right amount of power and still have a truck that's still easy to drive. I would recommend these injectors to anyone who needs to replace with new or someone wanting more power.

    just a little louder than double shots but i think it will be worth it for the power gain

    Finally, WOW what a difference these have made for my OBS!

    GOING from 17 yr old "AA"'s to these was like getting a new engine!
    She's alive and pulls the grades at 65mph, 2000 rpm, Air Conditioning blasting on Cruise Control!

    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.

    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!
    I'll be back for anything I need!
