i have a 2000 gt and i changed the plugs today it had the bosch platinums in it and i went to put the autolite 764 copper ones in and the thread is diff on the bosch and the autolites are diff the bosch ones have a longer thred so they would go in the cylinder better and the autolites cant be screwed in as far? now my car seems to run slightly off and isnt as peppy. anyone else had this problem and or know any answers?

There is another plug that is threaded longer that is the new replacement plug. It carried a motorcraftr plug number.

If anything the copper plugs should run slightly smoother. I haven't really had good expeirences with bosch plugs in Mustangs.

Honestly the Bosch plugs are junk and run horrible on are cars.I strongly recommend Motorcraft or Autolite
spark plugs they will work the best from my experiences.

Yes, the Autolite 764's will work. Plus they are copper a better conductor.
