I am upgrading to 740s and a fuelrail so have my new style JECs 555 with the ConceptZ old to new style injector kit already in the fuel stock fuel rail. I do have a couple extra backs of O rings that I am tossing in so if you want to reseat them in the rail or your rail you can. Short version is you are getting the following 6 JECs 555 injectors that ohm at 11.1. Coz kit Stock fuel rail New upper and lower oring if you want to remount the injectors in the fuel rail. I am guessing $400.00 shipped for everything but will consider your best resonable offer. Hit me up if you want pics
