New fuel injectors

I need to replace my injectors 1999 k2500 7.4L.
Has anyone done this?
The price range is all over the board!
$168 ea. New from dealer (AC Delco)
$104 ea. New from NAPA (Ecklund)
$148 ea. New from Carquest (Brand?)
$39 ea. New online (Bosch/Ford Motorsport)
$36 ea. remanufactured

All come with a 1 year warranty except the Bosch is for 3 years.

Are the AC Delco really that much better?

I have had good luck with the NAPAs.

Let me know what you find out, my 01 needs new injectors as well. Thanks...

I know it is a little late, but did you get the injectors?? How did you figure it was injectors??? I have a 7.4 burban

I went with the Bosch..see my reply on the other post.
I was pulling our travel trailer and going up large inclines the SES light came on with P0300 code and P0175 and obvious loss of power, I even had to accelerate going down grades it felt like the trailer brakes were on but I knew they weren't.
The dealer did a rich/lean check of sorts on each injector and they were all over the board. My pulling 5800# travel trailer mileage went from 9.7mpg down to 7. Let me tell ya, when this happens on the front end of a 3000 mile trip, it breaks the fuel budget bank in a hurry! Even in town driving after returning from our trip was 8.2 mpg.
I hope this helps someone else.
