Description Your choice of a Cleanable 8-Layer Cotton Oil Filter Element or Dry Filter Element. Both filters offer similar performance characteristics, so the decision comes down to would you prefer to throw away the filter (dry element) or clean it (oiled element). If your vehicle is under warranty, using a dry filter will keep the dealer from accusing you of not cleaning your filter properly. Also, both filter choices are cleanable but if you operate your vehicle in conditions with lots of dry dust, we have found that customers like using a dry filter since it can be blown out with compressed air to extend the life of the filter.
