• NGK have an extensive range of spark plugs to accommodate the increasing needs of modern engines
• Spark plug design must accommodate many features of an engine including physical dimensions, combustion chamber shape, cooling abilities, fuel & ignitions systems
• NGK have a selection of spark plugs to suit each engine & driving condition
• The 'S' type is the standard spark plug with a copper centre for quick heat distribution to prevent hot spots. The 'G' type has a smaller diameter centre electrode tip made of nickel which results in lower voltage required but reduced durability. The 'GV' type has an improved design for better gas flow & is better suited for racing situations. The 'VX' type has a small centre electrode of 0.8mm & a tapered ground electrode for better ignitability along with improved starting, idle stability & anti-fouling performance. The 'IX' type is similar to the 'VX' type with the use of iridium for an even smaller centre electrode without compromising durability. This type has the best performance in terms of starting, idling & throttle response.
