    They should be the same ICV between the M30 and M20.

    Also 3.6 M5 and later 635 i think

      I think he means AFM, just doesn't know what he is talking about.

      and its the one with the part number ending in 027.

        Yes , Air flow meter.

        has any one measured the area of the M20 air flow meter to determine if its really a restriction or are we assumeing it is?

          do some searching. rwh11385 has some dyno data that may suggest the M30 afm does little.

          I think . . .
