Oiled filters (eg K&N) can cause issues with the MAF as far as I know, although I've no direct experience.
The standard filter setup is a cold air intake though, so I don't personally see the point replacing it unless you need to because you want to go Stage 2 and can't route the pipework with the airbox in place. If anything, a typical air filter cone on the end of the MAF will just suck in warm air.
