Power loss in C15 engines is often traced to a clogged or leaking 3175278 injector. When the internal valve fails, fuel pressure drops, causing incomplete combustion. Replacing with an OEM-standard 3175278 restores the balance in the fuel delivery system.
Common symptoms include black smoke from the exhaust, difficult starting (especially when cold), and unusual engine vibration. Using the correct 3175278 replacement prevents fuel dilution in the engine oil, which can lead to catastrophic bearing failure.
