White smoke? Hard Start? Missing or ticking noises? No start at all? It could be that you have 1 or more bad injectors. Injector failure on the 03+ Common Rail Dodge Cummins trucks is usually caused by either bad fuel or the use of power adders that increase rail pressure. Bad fuel can cause injector failure immediately, pressure boxes will cause failure over time. The best insurance against bad fuel contamination is to run a 2 or 3 micron aftermarket fuel filter in combination with a water separator. We offer inexpensive options from Glacier Diesel Power and The Right Connection. For those of you that want to add filtration AND increase the fuel supply, we offer pumps from FASS, AirDog (PureFlow),BD, and others.

BOSCH ADVANTAGE: The advantage to being rebuilt by Bosch is they have the ability to completely "gut" these injectors from input to output to ensure they are as close to new as possible. The only "Remanufactured" part of these injectors is the housing. All internals are brand new and put together the right way by Bosch. There's no reason to pay enormous costs at the dealer.

Priced per injector. If you need a set, you will need to purchase 6.
