Many people don’t know that the choice of spark plugs has an impact on performance. NGK Iridium spark plugs are designed with the best technology for enhanced performance. NGK spark plugs are crafted with an iridium electrode that is smaller than nickel and platinum electrodes. This reduces the voltage requirement to extend the life of the ignition system. In addition, the metal shell plating is designed to resist corrosion for a longer life span and the best performance possible. NGK Iridium spark plugs can enhance the horsepower of your motorcycle for better performance. Iridium spark plugs have been shown to generate an additional two horsepower compared to stock plugs. Our extensive testing of NGK motorcycle spark plugs has demonstrated an advance of 2-3 degrees in timing and a more intense spark. To learn more about the horsepower gain found by switching to NGK spark plugs, watch our YouTube videos and view our dyno graph, which shows the increase in horsepower after replacing stock spark plugs with NGK motorcycle spark plugs. The difference is amazing for relatively little investment of time or money. The links to this information can be found in our Spark Plugs category.
