My LS recently broke what I'd assume was one of the original injectors, so I called up my O'Reilly guys to get me a replacement in (PN# FJ581). The one I received from them had a much different nozzle design (see picture) than the original, and what was advertised on the website (see picture). I know parts manufacturers can update parts designs, but when I tried the injector my car began heavily backfiring.
I returned the part to O'Reilly and ordered one from AutoZone (PN# 800-1593N) which now seems to be made from the same manufacturer. I've not installed the one from AutoZone out of fear of them not returning a used injector (My local AZ has a bunch of sticklers working there). Was I ordering two of the wrong parts this whole time or is this on the manufacturer for messing up? Either way, if anyone has ordered and injector for a B18B1 engine recently and it's worked fine, please let me know so I can snag one to get back on the road.
