Failed fuel injectors

[crr31c]

2005 Expy 5.4L triton. I had 2 fuel injectors fail. Ford replaced under warranty, but won't replace the rest, and not very confident the replacements won't fail again as well. Does any one know of a replacement/aftermarket fuel injector that addresses/fixes the failure issues that plaque the factory installed injectors. Looking to replace all 8 injectors. Any help is greatly appreciated.

I would leave them be and not worry about them. Drive till the tires fall off then get another one.
