With filters you either sacrifice filtration for flow or vice versa. The better ones are in the middle. Every filter is a restriction (running no filter is the best power you will get as there is no restriction).
People look into filter choice WAY to much. Thinking they will magically add a noticable amount of power changing from one to another (unless you had a really shit one in there before). I've ran my car on the dyno back to back with the filter removed and there was no difference so it must be doing ok - It's a Spectre one by the way.
All the major brands are just as good as the next; K&N, Blitz, Apexi etc. Just pick what suits your budget and what will fit well.
