Fuel system parts move more fuel, or move it more reliably, than the factory setup was built to. This one is the Bosch Bosch Complete Fuel Injector Service Kit 04.5-05 GM 6.6L Duramax LLY, listed to fit the 2004-2005 GMC Sierra 2500HD/3500HD with the 6.6L Duramax V8 (LLY).
why this one — On a diesel this is usually a reliability buy before it is a power buy. Match the pump to what the tune actually asks for. Diesel Power Products lists it at $3998.46, and the fitment above is what the listing itself states, not a guess.
