With more F150 and Raptor owners adding upgraded turbos to their trucks, we knew we had to design a way to allow for our AMS Turbo Inlet Tubes to fit with the larger Garrett PowerMax turbos. With a 64.5mm inner diameter, the AMS 2017-2020 Raptor & F150 3.5L Ecoboost Turbo Inlet Tube Couplers create a smooth transition from the larger 2.75? compressor inlets of the Garrett PMax. These are the perfect match to allow for more air into your new PMax turbos!
