The duratec is still classified under the zetec engine type. It is just a higher class model of the engine. Just as the svt engine is a zetec engine. So even if you are driveing a 2.0L zetec or a 2.3 duratec engine they are still the zetec clasification. the only one that doesn't fit is the split port or SOHC.
