Hard starts, rough idle, or a misfire under load often trace back to a worn injector on the LLY Duramax. The Bosch 0986435504 is a remanufactured stock-spec fuel injector for LLY Duramax 2004.5-2005.

Bosch supplies OE diesel injection hardware for these platforms. This unit restores factory fuel delivery when you want a genuine Bosch replacement rather than a no-name rebuild.
