      I'm glad to assist! The gap for the spark plugs in your 2005 Ford Taurus 3.0 VIN U is .044. The correct Part No. for your vehicle is SP-432. If you are looking to replace your spark plugs with iridium plugs NGK Part No.s 7397 and 6044, Denso Part No. 5325, Autolite Part No. XP104 or Bosch Part No. 9605. If you enter your vehicle information into the web site you will find many others as well.
