quick q on this - is it the maf sensor for all engines? i’m after one for the m5430.
No. It’s specific to the M models (e46 M3, E60 M5, E63/64M6, Z3M, Z4M).
For the Z4M, it can be found under [Fuel Management System]>[Intake Muffler] on RealOEM.

For the non-M, it can be found under [Fuel Management System]>[Hot Film Air Mass Meter] on RealOEM.

whilst the Z4M has a MAF sensor that can be replaced independently of the housing…the non-M one comes integrated in the MAF tube.
