Idiotic move by Cummins to use the CP4 in their 2019+ engines.
The Duramax is the smart diesel to get now, even with the DEF tank hanging off the frame like an ugly buck tooth.
The Denso HP4 is not without it's issues either in the medium duty world. We have had some HP4 issues come through our Hino and Isuzu dealerships.
The CP3 isn't without issues either, but it doesn't grenade the fuel system when it dies. How is the Denso in that regard?
