This is for a set of (8). This is not an exchange service! You send your injectors in to be rebuilt and receive back the same injectors that you sent in. You know the history and mileage of these injectors, keep them! These get all the major wear items replaced such as nozzles, nozzle lift spring, piston return spring, all seals and gaskets, plus the spool valves are polished and all sealing surfaces are refinished. These are all bench tested on our Hartridge HA-230 flow bench once completed to ensure all flow rates and functionality. These include a 6 month warranty.
