Will I have any problems if I switch to iridium Spark Plugs? Should I consider adjusting idle speeds, using regular gas instead of Premium gas, (my dealer insists on the use of premium gas with the copper core plugs), or anything else?:smile::smile::smile:
Genghis, Due respect, but those plugs are used in ultra hi po ,high compression engines. Why spend $8 per plug for engines that run at fast idle. Or are you pulling our leg? How "bout aviation gas?:laughing:
