I have had three Dakota 3.9L using WIX Radial 42020 Air Filters, they all have come with a pre filter, I like the pre filters, I replace them at every 3 month oil change, wash/clean the dirty pre filter and use it again, it prolongs the life of an air filter and is especially good in dirtier environments such as driving on gravel/dirt roads and working in construction areas. {if you check the WIX or Napa filter sites it list the pre filters available and their matching air filters}
