Ask your dealer for sure.

l would not use them.. l would go to ford and buy motor craft or go buy some auto lite plugs for you car buy specs. they can look that up when you buy them.

ur best choice is at ur dealer it will cost u more bu it tottally worth it

You do not need to go to the dealer go to your nearest auto parts store and ask for motorcraft plugs for your car then replace and see for your self you should be ok, hope this helps.
