for 10-12 more bucks online you can just buy a set of 8 motorcraft/beru's and save the guess,as to if they will last,or worst swell up in the head and break off when you go to change them, causing you to lift a motor,pull a head or two,replace head gaskets,and other gaskets required,and that's after the hard work of extracting the things,or paying a machine shop to do it.
