Over here in the good old'e USA, NGK9's are still available at a hell of alot cheaper than in the UK (Where they're hard to find now). Iridiums also seem cheaper, but I need to know the Part Number for the Iridium equivalent/replacement for the NGK 9.

Anyone know the part number ????

Everythings bloody cheaper over here..... God we do get ripped of in England for car parts.
