Ok, this might be pretty boring, but here goes............
DPFE sensor's, Coil Pack's for the gassers.
Cam sensors, fuel bowl heater, UVCH, for the 7.3's.
Head Gaskets, IPR sensor, power steering cooler lines, EGR cooler and Valve, and sticking turbo vanes for the 6.0's.
But I am pretty bias, and did not think to long about this either.
