Anyone know the stock injector size in cc for the E46 325 and 330? thanks

When one says injector size difference is there a difference in physical size of the injector or the difference in fuel flow?? Sorry i am blur on this. Want to know too.

I have checked realoem to compare both m54 engine parts and they seem to be the same part due to the same part number... this is for the fuel injector/valves.

The only difference i see between the both 2.5 and 3.0 is under the fuel injection system - throttle housing assy.... anyways below is linky... both m54

Another question is if you want to upgrade your injectors what is changed??

Thanks

325 and 330 injectors have different flow rates. For the 325 its about 17.8 lb/hr. 330i more than 20lb/hr

Bundy,
17.8 lb/hr = 134cc injectors
20.0 lb/hr = 151cc injectors

I hope my conversion is correct.......

Injector size refers to the flow rate not the physical size.

and if you want to change injectors, just get the ones that are for your car together with the size you want. Simple plug and play. But you do need to have your ECU can handle the large injectors.
