It's a wix filter, those are pretty much what all top filters are.

Why spend 10-15 bucks on a filter when a napa gold for $3-5 is just as good?? To me it's a waste of money to buy a K&N filter or mobil one filter, you are just paying for the name.

They are designed for 4-5k mile oil changes, they even sell a platinum filter for 8-10k mile oil changes.
