kanggwan Posted May 1, 2009 Share Posted May 1, 2009 Hi there I have just changed my spark plugs and noticed that the plugs I was given are different to those I took out (both sets are champions). the ones I took out are RN11YCC'S and the new one's are RC11PYPB4's (a label stuck on the outside says they correspond to NLP100320's). I noticed that the new ones have a very thin looking central pin. Any advice? Thanks Stewart (PS driving a DII, 2000, 3.9) Quote Link to comment Share on other sites More sharing options...
