yeh they do fit if you have the head machined and tapped , the only problem is that the cossie plugs sit slightly lower in the head so the have to make sure your leads are on by really pushing down hard until you hear them click , this causes misfire under boost which if iam honest was a pain in the arse. now i use standard ford focus rs plugs which have been provern to 500+bhp

hope this helps

cheers paul
