The DDP LB7XXNZ High Flow Injector Nozzle Set for your 01-04 GM 6.6L Duramax will make your truck fly. With the Allison 5 and 6 speed, the Duramax is already fun to drive. Why not add an additional kick with DDP Injector nozzles. Unlike an electronic box, honed performance injector nozzles are almost impossible for a factory technician to detect. With DDP’s Balance Honed injector nozzles you can be confident that your warranty will not be compromised and you’ll have the extra pulling power to beat your friends up the mountain.

The 50 horsepower nozzles will give you 50hp at the wheels. You can use these in conjunction with an aftermarket electronic box or downloader without the worry of draining the fuel rail dry. We do not offer a 90hp version because we feel that 50 is the largest you can do without needing dual injection pumps. These injectors work equally well in a completely stock truck.
