The DDP 305-XX High Flow Injector Set for your 03-04 Dodge 5.9L Cummins is able to offer what no other upgrade on a Dodge Common Rail can provide, the stump pulling torque that a set of Dynomite Diesel injectors can deliver. Some of the electronic boxes available today can actually crack your injectors, causing thousands of dollars in repair bills. Be confident that you have a mechanical change that will add reliable power, without the headaches. If reduced smoke, more power, and better mileage are what you are after, then you have come to the right place.

50 HP injectors have been used on trucks making over 600 horsepower on fuel only. If you are looking for a mild upgrade with the potential to make great power, then these are the way to go. If you have to make big power and care less about mileage and smoke, then we recommend the 90 horsepower set. As always, this product is covered by a 1 year unlimited mileage warranty.
