MGZR 160VVC Spark Plugs...

Hi Guys,



I have come across a pack of spark plugs in my garage that I must have purchased for my MGZR (unless they were for my ZS??) - they are the following:



BKR6EIX11 Iridium IX NGK SPARK PLUGS - any ideas? I checked on the main NGK website and now I am really confused as that website shows the following for my car: 'Standard PFR6N-11'??
