‘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. | |
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. |
