Carquest premium remanufactured injectors are completely torn down, ultrasonically cleaned, inspected and remanufactured using premium components. Carquest Premium Cummins 5.9L injectors are updated to the latest design revision to reduce failure modes that are common with the original design. Each injector is 100% tested on a sophisticated automated flow bench under multiple operating parameters to meet or exceed OE specifications. This Carquest six-pack includes six premium injectors and six fuel inlet tubes, which should be replaced any time the injector is serviced or replaced to reduce potential injector failure from contamination. The upgraded design of the fuel inlet tube includes several features such as a larger sealing surface to improve sealing between the fuel injector and inlet tube, an integrated edge filter and improved alignment pin.
