Just clean the maf, and the filter (don't oil it), and you should be fine. The cold air intakes move so much more air through the system than the stock filter, that it will literally suck out any excess oil out of a filter (or microscopic dirt particles) out of the filter immediately on start up, and there goes your MAF sensor.
I will do a write up before the end of the week. Crazy crazy week, track event today, and a couple cars that need to leave town by friday, so it is a little crazy, though I will get it done
What you will need:
Can of CRC maf sensor cleaner (any auto parts store) or CRC QD electronics cleaner
Torx security bit (though with the cold air intake system, this probably has been removed and replaced with a small 2.5 or 3mm allen)
