THE BEST SPARK PLUG FOR EVERY OCCASION As a result of our policy of continuous research and development NGK can offer special spark plugs designed to give optimum performance under a high range of conditions. ‘S’ TYPE (e.g. BP6ES) NGK standard spark plugs with 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. Copper cored electrodes also mean that longer insulator noses can be used to protect against fouling. ‘G’ TYPE (e.g. B10EG) These plugs feature a smaller diameter centre electrode tip made of conventional nickel alloy. The smaller diameter centre electrode means the voltage required to produce a spark is reduced. However as the tip is made of conventional nickel alloy the service life is reduced and these plugs are best used in applications where plugs are frequently changed. ‘V’ TYPE (e.g. B10EV) The centre electrode of this type is made of gold palladium alloy and is even smaller in diameter than the G type at 1.0mm and has therefore an even lower voltage requirement. These ‘V’ types have now been discontinued and replaced with ‘VX’ or ‘IX’ equivalents. ‘GV’ TYPE (e.g. B9EGV) These plugs have a centre electrode of precious metal similar to the V range. In addition the insulator nose is an improved design to allow better gas flow around the firing end. The ground electrode is shorter and stronger, making the GV range more suited for racing applications. ‘VX’ TYPE (e.g. B8EVX) These plugs have an even smaller centre electrode (0.8mm) than the V types and this is made of platinum. This combined with a taper cut ground electrode means an even lower required voltage than the V types. The result is better ignitability along with improved starting, idle stability and anti-fouling performance. ‘IX’ TYPE (e.g. BR8EIX) Similar in design to the Platinum VX spark plug, the use of the precious metal Iridium allows us to manufacture a spark plug with an even smaller diameter centre electrode (0.6mm) without compromising durability. This extremely small Iridium tip centre electrode concentrates the available electrical energy and combined with the taper cut ground electrode provides the best performance in terms of starting, idling and especially throttle response. 4
NGK spark plugs are designed using the latest technology to give optimum performance over the engine’s entire rev. range. Fitting the correct type of spark plug is essential. Many changes in engine technology has meant changes in spark plug design. Some NGK spark plugs may have a similar appearance, however the internal and or external design can differ sufficiently to cause engine damage should the incorrect part be installed. The examples below display some of the different design features employed in typical motorcycle applications and hopefully help to explain the reason for some application specific part numbers. CR8EH-9 • Used on some Honda designed engines • Special thread can only be used in specific engines or the cylinder head will be damaged CR6HSA • Centre electrode is 0.2mm wider than CR6HS for improved durability • Short metal shell design ER9EH • Used by Honda, Ø 8mm thread with 13mm hex • Do not exceed the tightening torque of 0.8 - 1.0kg/m FITTING THE CORRECT SPARK PLUG Ø 8 mm Not threaded 6.3mm Threaded 12.7mm Not threaded 6.3mm Threaded 12.7mm BR10ECM • Compact style, mainly used by Honda and Suzuki • For use where space is restricted CR9EK, JR9C • Used by Kawasaki and Suzuki • 2 ground electrodes for improved durability B9ECS • Short ground electrode for strength and to prevent overheating • For competition use CR9EK thread diameter Ø 10 mm JR9C thread diameter Ø 12mm 18.5mm (B-ECS is 6.5mm taller) 17mm (B-ECS is 3.0mm taller) 5
