Eh, maybe something like this. But it sounds like you might have done something like this already. u/bsb2001ca was right though, MAFs are real sensitive. I bit the bullet on an Injen CAI which puts the filter outside the engine bay and sounds NOICE AF, but yeah $370.

ALSO For the P0420 code ( u/representative_egg46 ), scew tuning, get you some of these suckers (any brand/store). Simple and effective. You slap it on the downstream o2 sensor (only). It puts the sensor out of the "line of fire" and in turn reads less emissions. It was an immediate fix for me. ...and jk about tuning, tuning is amazing...but a simple $15 fix for check engine aint too shabby.
