Bad idea, unfortunately.
Our Nissan/infiniti engines use hot-wire MAF systems. If micro-droplets of oil get into the air-stream, these deposit on the MAF, and, in time, burn themselves onto the sensors. Causing driveability problems.
Yeah, there are people who think this is not a problem ... but they have rarely kept the cars long enough to discover this issue over time. The usual comment seems to be "I keep it very dry - not dripping with oil", but the fact is that you will get some oil into the air flow no matter how hard you try!
Basically, the small gain in performance is simply not worth the risk - better to just change the stock air filters regularly!
