🔧 Why Replace the Full Set?

On high-hour Cummins N855 engines, injectors wear at similar rates. Replacing only one or two leaves mismatched fuel delivery across cylinders — causing uneven combustion, accelerated wear, and recurring issues. A full 6-piece replacement is the professional standard for overhauls and ensures balanced performance from the first start.
