Has anyone actually installed these? One seller has 37 positive reviews for the injectors. I just recently discovered dcec the company in china that cummins owns 50% of and supposedly they make really good parts. I wonder if they are manufactured by them and relabeled Bosch. The boxes in the pics have Chinese writing on them but since my Chinese is super rough as in non-existent I have noooo idea what they say. I know what youre thinking, im thinking the same thing but how has no one from Bosch sued them for product and labeling copyright and patent violations. I do know cummins and DCEC sued a bunch of the knock off Chinese parts vendors in china. They went around at shows and inspected the distributors booths and notified them on the spot that they were going to sue. If I had an older junker that I didn't rely on daily for work id buy them without a second thought based on the reviews just to see if they worked like the reviewers said.
