Hey
Whats the internal diameter of a 325i AFM?
Is there any difference between the 325i AFM and the 320i AFM?
Thanks
Antony.

325 84mm
320 80mm
but if i am wrong someone will correct me!!!
so yes the 320 is smaller, common mod to fit the 2.5 AFM to the 2.0 to get a bit more umph, do a search there are plenty of how to articles

Thanks for your help, but thats the throttle body.
AFM = Air Flow Meter, Its the bit attached to your air box. Before the throttle body.
