Lesson learned, your better off to buy new!! I ordered injectors for my 6.7 and 3 failed immediately after installation. I talked to the technician and he said that never happens. Sure enough after my mechanic removes them , I ship them back for testing 3 faulty injectors. I had to pay again to have to reinstall. Cost the same as buying new. Very dissatisfied.
