NGK are the world leaders in spark plug technology, it naturally follows that the world's motorcycle manufacturers make NGK products their No.1 choice for OE fitment. Designed using the latest technology to give optimum performance over the engine’s entire rev. range. For many Yamaha Motorcycles there is a choice of NGK spark Plug:- NGK Standard Copper Core - Copper cored centre electrodes for wide heat range. Copper’s superior heat conductivity dissipates the heat of combustion away from the firing end, preventing hot spots that can lead to pre-ignition. A wide heat range means the spark plug performs well with either a hot or cold engine. Performing well at high speeds as well as low speeds, and stop go riding i.e. city riding. Copper cored electrodes also mean that longer insulator noses can be used to protect against fouling. NGK Iridium IX - Benefits from the use of the precious metal Iridium on its centre electrode. Iridium is harder than other precious metals used in spark plug manufacture, has an extremely high melting point and offers greater protection from chemical attack. These features allow the use of an extremely small diameter electrode (0.6mm) without compromising the spark plug’s service life. Combined with the use of the taper cut ground electrode this spark plug has superior gas flow properties and lower voltage requirements, which offers further improvements in:- starting, idling, throttle response, enhanced ignition efficiency, better acceleration, faster starting & smoother running, longer life and better fuel consumption. NGK Laser Iridium - Provide superior ignitability and long service life. NGK Laser Iridium offer:- slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions, laser welded Iridium centre electrode tip, platinum disc welded to backside of ground electrode provides long life, trivalent metal plating for superior anti-corrosion and anti-seizing, faster starts and quicker acceleration, better fuel economy and lower emissions, best OEM Iridium spark plug available and Original Equipment Manufacturer approved design.
