  • I'm doing an engine swap on my 2004 Chevy Tahoe Z71 4wd. I'm going from a 5.3L to 6.0L with 450hp . I would like to use my OE harnesses and fule rail. Would these injectors work and are they enough LB ? Thanks for your time and help.

    The injectors flow rate will work for your application, but you will need to check the your intake and fuel rail will fit the 6.0L engine has a different style manifold.

    Are these able to fit a 2013 GMC Sierra 5.3L with Flex Fuel? And will I gain much power?

    Asked by: Urby4699
    These should work for your application. They do not make more HP by themselves, they just do a better job of regulating fuel flow and that can lead to more HP.

    Will these work with 2003 LQ4 6.0?

    Asked by: CharlieG
    As long as the ECU is able to drive this set of injectors.
