the filter may let more air pass.... but you are only as good as your weakest link.
the stock filter box may not be able to let more air pass. personally i think the stock intake is fine for most people.
if you dont know to much about cars or want to deal with any problems at all i would get a good filter and ram air scoop. there a bunch to choose from now (swoop scoop, rpi ram air, and afe ram air.)
any questions pm me
