Howzit guys, Has anyone on the forum tried running their RS250/265 with normal platinum plugs? I know the 3 electrode plug the RS225/230 uses will fit a RS250/265. Just need to know if it has been tried before and what the outcome was. Cheers
Only use iridium never actually done an A/B test With 3 electrode plug can’t change gap from factory setting
stick to oem I had iridium and for a long period of time I was getting random top RPM missfires. Tuner friend of mine advised me to do oem only for oil filter and plugs on mk3
