If you just want stock injectors, find someplace that sells Alliant injectors. Many diesel or turbo repair places carry them. A stock injector should only cost about 200.00 plus core. David at Diesel Innovations also carries them I believe.
Why do you think yours are "DUE FOR REPLACEMENT"?? They can last 300k miles with proper maintenance, (oil changes, fuel filter changes, good fuel ect...) And on the other hand, even with those things you can have one fail at 150k...
However it's rare that you should have to replace the whole set,,, if you have one bad, just replace that one.....
UNLESS of course you want to upgrade to a performance set...
