Iridium Vs Copper

With Iridium re-gapping is infrequent or eliminated. In fact, the initial reason this type of plug was developed was an attempt to meet the 100,000-mile durability/maintenance requirement mandated by the US EPA for exhaust emissions, not because they offered any improved performance over conventional electrodes. Platinum or iridium plugs will give you worse performance than a conventional plug unless you use a larger gap than is recommended for the steel electrode plug equivalent. If your China bike is going to go over 100,000 miles on the engine or longer life than that then you might want to invest in one, otherwise the design of the iridium plug was to seperate you from your money.
