Having run oiled filters on several other cars with MAF sensors they also bring about another issue: the oil residue eventually builds up on the MAF sensor causing faulty readings.
Usually not too hard to fix but it means that for optimum performance you need to remove and very carefully clean the MAF sensor to remove the oil residue at some point for continued accuracy. I got to the point where I would clean the MAF sensor every oil change but it usually takes a good bit longer for problems to show up. Usually will manifest itself with reduced fuel economy, slightly reduced power, poor idle, and a MAF sensor code when it gets too coated in oil.
