Quick N53 injector question(s)

jerry486 · 11-12-2024, 08:58 AM

N53 engine, 2008, 3.0 petrol

Is index 11 the highest index that is supported? (13537589048-11)

Is it true that if I were to put an index 11 I would need to ensure the whole bank 1 (cylinders 1-3) are index 11's?

Thanks in advance!

I run 12s on my n53 (with stratified charge). I've always read they need to be same index, but the more I think about it, why would they? As long as they are not leaking, and programmed to the car, it should be fine. I believe that myth is refuted somewhere, maybe by bimmerprofs(?).
