Product Description
The DDP 325-300 Injector Set is the largest fuel delivery option available from Dynamite Diesel Performance for the 2004.5–2007 5.9L Cummins. These 300% over injectors are engineered for extreme racing applications where maximum fuel volume is required. Built from brand-new Bosch OEM injectors, they are professionally modified and flow-balanced to ensure consistent and reliable operation under the most intense conditions.
