OEM Denso 6.6 Duramax L5P Fuel Injector Core Charge of $150 Applies

MIA's Description

If your L5P Duramax has been down on power, idling rough, or throwing injector codes, there's a good chance it's time to swap in a new set of injectors, or at least replace the one that's failing. The Industrial OEM Stock Fuel Injector is a direct-fit replacement built to the same standards as the original Denso injector found in 2017–2022 Silverado and Sierra 2500HD/3500HD trucks. Whether you’re chasing a drivability issue or doing preventative maintenance on a high-mileage workhorse, this injector delivers factory-spec performance and reliability you can count on.
