Hi There

Looking at NGK spark plugs for my standard 3.2 all web sites list NGK IFR6 D10 (including NGK UK site & ebay sellers) but I'm sure I've seen on this site some owners use NGK IFR5 D10 on standard 3.2. Also most sites list no difference between 3.2 and supercharged models for spark plugs. Is this right?
Thanks for any help


Cheers
