Product Description
Shop with Blessed Performance for the DDP Injector NOZZLE SET 45% OVER 75HP for 2001 to 2004 LB7 6.6L Duramax diesel pickups.
Note: The fuel injector lines on the LB7 are notorious for rusting and causing issues with the injectors. For this reason it is highly recommend replacing your injector lines while changing injectors or nozzles if the lines have not been changed within the last 40,000-50,000 miles.
IMPORTANT NOTE: All nozzles should be installed and the injectors calibrated by a professional shop that is familiar with calibrating over sized injectors. Due to the massive variations in calibrations of injectors from other manufacturers, Blessed/DDP cannot guarantee you will see the stated horsepower gains unless the nozzles are installed by Dynomite Diesel and all other supporting modifications are in place.
