I think that if you just want more air, use the stock filter.lol
The better the media in a filter, the more restrictive they will be. More surface are helps a little to counterbalance that problem, but more air is not a definate in these. Some claim more cfm, but its really hard to achieve with a 100% better filter replacement. Better look at studies and proof before you buy if airflow is what your looking for (no matter what brand it is).
