I'm with your Dad on this one

Sometimes these aftermarket air filters release some little 'fuzzies' which end up in the MAF and messing up its calibration, or people over oil the aftermarket air filter and contaminate the MAF with filter oil.

And then they put their stock intake back on and 'prove' to their Dad that, "See, it does it with the original air filter, too!"

Cut the guy some slack - he might just be smarter than you give him credit for.
