Related to OP's inquiry, what is intended to be the point of the snorkel? Agreed that the lack of the snorkel should have no impact on getting dust/debris to the MAF; the filter should have prevented that. @junkley, is it possible that your air filter wasn't positioned correctly or that there's a leak that's allowing air past the filter?
No snark intended on this end. Just trying to 1) learn why Porsche installed the snorkel if it's extraneous, and 2) hopefully help spot why @junkley had dirt in the MAF.
