How much has a CP4 failure cost you before?
Ford continues to put the CP4 in the 6.7L Powerstroke. While the CP4 service life can be improved with fuel additives and making sure clean fuel is used, the CP4 will always carry the potential to wreak havoc on the entire fuel system. Complete fuel system failure can easily cost 12k or more. While the DCR is the best option to get rid of the CP4, it is important to at least have a disaster prevention kit to help prevent complete fuel system failure if the CP4 comes apart.
