I'm going to do this mod however I want to make the right choice.
The oiled filter has 75% better air flow over stock and the dry filter has 50% better air flow over stock. Personally, I wouldn't want to deal with re-oiling the filter after cleaning it so I would go with a dry filter. I highly doubt I would notice a 25% difference in air flow, but who knows It all comes down to personal preference. Can't go wrong with either choice though.
