Review on Zreneyfex Injectors Bosch Upgrade 8 Pack by Richard Edwar

2000 C3500 7.4, installed these jets, they were noticeably slightly different from the ones I removed, but all o-rings, inserts and sizes were the same. Once installed the truck runs great but now it has bank 1 and 2 engine codes working for the rich. For that reason I wouldn't recommend them, now I'm ordering another set of injectors and have to buy new seals and spend another weekend just replacing those injectors. I've never had engine codes and saw another review before doing mine about these codes. I just want to let people know that there is a chance you may have the same problem.
