Hi all,does anyone have any info on when plugs should be changed on a 2006
JCW R53.Its just had its second service at 20K miles where i was told its not due till the next service which would be an inspection 2.I know this is correct for an S but doesnt the
JCW have more frequent plug changes? If i wait till the next service the original plugs will be 5 years old as i dont do loads of miles.Surely this cant be right.
