Yes. the Fiesta ST uses the same air filter as a non-ST Fiesta. Ford part number FA-1914 in the 2014 Fiesta owner's manual and on www.fordparts.comI've been looking for a K& N filter for the FiST, but was wondering if the filter listed 33-2955
for ALL 1.6 litre engines is the right one for our cars. Anyone changed theirs out yet and KNOW?
