    I think for the price and you are wanting to start customizing and working on your truck the AIH is a great start and you don’t have to be the best mechanic!

    Great upgrade

    The RDP AIH tapped plug is a great solution for removing the obstructive AIH, is a convenient port for a boost gauge, and looks great! Always one of the first upgrades I do to a 7.3

    Strong construction, accessory ready

    Replacement threaded plug for the AIH (Actuator Injection Housing). Allows accessory installation or repairs without compromising internal pressure.
