they create a better,sharper,stronger spark i suppose.......
Bill, I heard or read that iridium plugs arnt as long lasting as platinum etc plugs apparently so Im expecting to change them again (if i still have the cupra) in 20k.
yes but as good as a definition that is mate how can anyone prove that they can feel that difference/what does that difference even feel like?
40 quid my arse, i paid 24 quid (maybe 26 i can never remember!) for them locally.
i'm curious to what people define as an improvement over standard plugs?
26 quid for what plugs?
NGK iridium plugs
