No, recently had the bike deresrticted and the old ones were soiled bad from 2 years of restriction. Mechanic changed them but didnt have the correct type in so used some others (did the job but not running to 100%)
Said I just needed some new ones so I bought iridiums and tried to change them but it ran worse with them in

bought another set just incase it was a faulty pair but no joy.
Looked in the manual and bought the type it recommended (not iridiums) ran even worse.
£50 on plugs and still no joy -.-
