Although you are correct in that K&N is a brand and not a style of filter, after that you display nothing more than your vast internet automotive expertise, which is to say none at all. Intake flow reversion is not a problem with any MAF on a stock or near stock engine. Not until you start running huge duration numbers, extremely tight LSA's or a combination of the two. Even then, the MAF isn't the problem, the problem is the the ECU/ECM/PCM being confused by unexpected inputs. But I digress.
No Skippy, what Doug is talking about is how reusable/cleanable/oiled cotton gauze filters are notorious (some brands more than others) for contaminating the hot wire in the MAF, causing drivability issues and DTCs to mysteriously appear. That is why they're not recommended by several OE's and are covered in a lot of TSB's from most manufacturers. Anyone with the slightest hands on experience knows that. Leave the technical stuff to those who know. You can busy yourself with "stylez".
Have a nice day.

Oh and as for "K&N" and MAF's. K&N is a brand, not a filter style. Whoever you heard that from was anidiot anyway (or you are if you just made it up). The issue is with removing the stock airbox and piping, not the type or brand of filter. If the MAF is located close to the throttle (which is ISN'T on his car anyway), there can be issues with intake pulses/reversionscrewing with the signal at lower RPM. These issues are rare-to-non-existent on most cars and are usually a result of aftermarket intake pipesmoving the MAF too close to the throttle body, NOTbecause of some particular brand or style of filter.
