I had switched to a K&N on my mustang and was concerned about the MAF getting fouled but it never effected it
I think you need to see what residue maybe lurking in your throttle body and using some MAF cleaner.

I've used K&N air filters on my Z3 and Z4 without any issues. Porsches and Ferraris are not recommended as the oil particles from the filters will foul up the sensitive sensors. You might get lucky based on how much oil your filter has on it, but its a guessing game and luck at this point. No thanks, not worth the gamble.
