the color above looks like granite silver.
Not sure if it was answered but you want the B40 mafs, the b30 is smaller (same mafs used on b30 and m50b25).
When i had my 530iT i swapped a b40 intake manifold, throttle body and mafs (and software), it's been shown to be worth about 18-20hp at the wheels on a b30.
