Default 50lb 6.0 FLEX truck 12613412 injectors

So these injectors are all over the internet and look legit, but I assume a lot or most are knock off China junk. Anyone know the story on these and how to tell if they are real vs just buying a AC Delco or GM part from the dealer.

Just buy them from a GM parts supplier if those are the ones you want. Check out #12609749 - you might find these are a better choice.

Only buy from a trusted brand, sometimes the only way you can tell is only when you have it in hand and can actually see quality flaws, and of course when you put them on the flow bench.

As mentioned above 12609749 is the newer Flex Fuel injector that was used in the later NNBS with the flex fuel 6.2s....they flow slightly more at 54lb/hr@58psi
