Angry IMPORTANT: 7.3L Gas - Ford Technical Service Bulletin 20-2370 Plug Wires

Much has been said on various threads about problems with the spark plug wires on 7.3L engines... I just want to bring this to the front again because neither Tiffin nor Ford let me know; If I had known, I certainly would have changed plug wires as a preventive measure before breaking down and having to leave my motorhome abandoned in a fire evacuation zone.

NOTE: If you have a 2021 Tiffin motorhome, it may be built on a 2020 Ford chassis and this Technical Service Bulletin may apply to you!
