Copper spark plugs
Been a member for a while, but this is my 1st need for relatively urgent advice. Posted on existing thread, but hoping a new one might get a better response.Have checked several threads and other Google searches but couldn't find a satisfactory answer, so sorry if this seems a bit silly...
I ignorantly bought Bosch FR7DC+ Yttrium and UR6DE Copper a long time ago, so can't exchange them. Never got around to putting them in until now, but only just clocked 62k miles. Would I be better off leaving the factory plugs(I assume) in,or maybe cleaning them? Or replacing with my new 'inferior' plugs? Have read copper is not recommended for TS, but can they do damage? Thinking of changing car so don't wanna spend on new OEM plugs.
Also its a 156 1.6TS CF3, which I think is not a wasted spark system, if that matters..?
