the only problem with the zetec engine, is that if you have an aftermarket intake on it, it may rub a little. i have not fitted one a set of these on a car with a zetec yet...i had a little rubbing with my KKM at first, but i fixed it, but i still have a little mark from where it rubbed. it is not too noticable unless you like to stare and nit-pick at it....
