Hi all. Can anyone recommend which spark plugs to fit in a 2002 2.5ltr v6 S type jag. I have removed the current plugs which as the car has only done 40k are the factory plugs. I have looked everywhere and can’t find same plugs and have been told by the Jag dealers they are no longer available and offer a different plug which has a full length thread. If anyone has fitted an alternative plug I would be very grateful to know what. Many thanks.
