Incorrect!
AWSF32PP or Autolite APP764 are recommended by this site. (AWSF32PP or AWSF32F are original depending on year - another Ford decontenting IMO!
)
AGSF style plugs have a slightly longer end that sticks into the chamber a bit more. They dealership will try to sell you these for any Duratec even though they have only superceded the 3L Duratec (all years) and are stock in 01 & newer 2.5L Duratecs.
While I will gladly state NGK makes excellent plugs they sadly do not make any double platinum plugs for the Duratec. Expect to change them 2 maybe 3 times as often as the listed double platinum plugs. More often yet if you are chipped!
