Dunnel's site is a little confusing there is a list of parts descriptions and a list of thse parts by part #'s and their prices, if the part # isn't listed on the price sheet you have to inquire my email. They do make some very tasty bits fo rthe Zetec and about 99% are good on our engines if you can "improvise" here and there. Check out Burton Power and Need for Speed they also have a wide selection of goodies for the Zetec.
