These are brand new Bosch, no core required, factory injectors. Not a single remanufactured part goes into these, as they are direct from the manufacturer with the latest upgrades included.

This type of injector is pretty difficult to come by, as the majority of Common Rail Injectors available are considered Remans. While these are still a great injector, the bodies and some internal parts are essentially used. Where as these particular injectors are truly new injectors from the original manufacturer, just as came in your truck when it was new, only with all of the latest upgrades performed. Injectors are sold individually, so if you're in need of an entire set, don't forget to order quantity six. When installing these, we recommend also replacing your Connector Tubes at the same time to discourage the potential for any leakage.
