I have a bad injector in my 2012 3 iTouring Sedan with SkyActiv and I am planning to replace all 4. I can't seem to locate the correct (SkyActiv) replacement part number? I've found conflicting information online. For instance, Rock Auto will show a part that fits SkyActiv engines, but when I cross-reference the same exact part on a different site, it will say it does not fit SkyActiv engines. I'd like to avoid purchasing from a dealer and paying super high costs. The car has 153k miles and although it's been a great car, I've had to put about $2k worth of parts into it during the past year or so and I'm not sure how much longer I can rely on it. If anyone can point me in the direction of "budget friendly" replacement injectors that would be great. Thank you.
