Theres a few companies that have reusable air filters. K&N is one of the more famous ones, but they all perform about the same. from testing, I believe K&N holds the most dirt before choking, but isn't the greatest on flow, or dirt filtration as other brands. Paper filter has the best filtration, but it's too costly in the long run. I'm running K&N in really dusty climates, and haven't had much trouble. Needs to be cleaned soon. I don't know of amsoil makes one or not. a few top brands make reusable air filters. The thing I like about it is less trash piling up from filters, and K&N has a 10 year/million mile warranty. If you don't like K&N, there's a few out there that make an equal or better filter. Just browse and see what you like, and then compare.
