You'll need to know the engine size of your 1998 Ford Windstar to determine the correct oil filter. The Windstar came with a few different engine options. Once you know the engine size (it will be listed on your vehicle's identification plate, usually located on the driver's side dashboard or doorjamb), you can consult your owner's manual or an online parts store like AutoZone, Advance Auto Parts, or Napa Auto Parts. Simply enter your vehicle's year, make, model, and engine size to find the correct oil filter.
Alternatively, you can take your old oil filter to an auto parts store and they can cross-reference it for you to find a suitable replacement.
