Chevrolet Duramax Stock Fuel Injector - DDP - 01-04. A brand-new, OEM-style replacement injector for 2001–2004 6.6L LB7 Duramax diesel engines, sold individually to restore proper fuel delivery and drivability.

DDP's stock injector is manufactured to match factory specifications for fit and function on LB7 platforms. It maintains stock flow and spray characteristics so emissions control, fuel economy and engine management behavior remain within intended parameters. This injector is intended as a direct replacement for worn or leaking units, helping recover smooth idle, reduce rough starting and restore consistent fueling without altering engine calibration. Sold as a single unit so you can replace only the injector you need while retaining original engine characteristics.
