Hey guyz.....I was wondering if anyone knows if ALL M50 intake manifolds are the same? Is the 325, 328, and not to be left out, the M3's identical? Thanks!

They are the same, but M50 (OBD1) and M52 (OBD2) are different. The OBD1 manifold is the better one, but will not fit M54 engines due to different style intake ports.

For one, you need to switch the studs, but the port shape is totally different, so while it may bolt on, the intake ports are not compatible and may create turbulence issues.

(M50 intake ports are oval)
