Air Filters - Reusuable: As an alternative to Paper Filters there are also a large number of aftermarket reusuable air filters and manufacturers, each having their own claims, pro's and con’s. One of the biggest pro's would have to be the 'reusable' factor that a lot of them have to offer. Not only does this lower the cost of maintaining your car, it also eliminates another item you have to replace at your next service.
