The aFe Momentum GT intake replaces the factory airbox on the 2017-2019 Super Duty 6.2L gas V8 with a one-piece housing, a Pro DRY S filter and an intake tube joined to the throttle body by a silicone bellows coupler. The filter uses three-layer oil-free synthetic media that is cleaned and reused without oiling. A plug is supplied to close the housing's extra inlet, which blocks hot engine bay air and lowers intake noise, and an optional scoop (54-73006-S) is sold separately.
