Thinking about going back to copper resistor type plugs, and was wondering if anyone has any thoughts about this subject. But, while it is fairly inexpensive compared to comparably conductive materials like silver, copper is also extremely susceptible to heat damage and corrosion. Along these lines, they work ideally at a much lower temperature, enduring in an average of 40,000 – 60,000 miles (contrasted with copper). Spark plugs with a hotter heat range will burn off carbon deposits more easily than a colder plug. Per … Remember, the smaller the diameter is , the lower the voltage is required to start a spark. Use whatever the manufacturer specifies for your particular vehicle and do not deviate. I know the Iridium last a long time, but that really isn't an issue, plugs are cheap and easy to change. No, following the appropriate change schedule, I believe 30k, though I did it more frequently, maybe 25k.
