NGK Spark Plug CPR8EA-9 Plugs [Box 10]

The NGK Spark Plug CPR8EA-9 is specifically designed to accommodate the ever-increasing demands of modern engines. With a wide heat range, these spark plugs are suitable for both high-speed and low-speed driving, making them ideal for city driving or fast motorway cruising. NGK's spark plug design takes into consideration physical dimensions, combustion chamber shape, cooling abilities, and fuel and ignition systems, ensuring maximum power from an engine while keeping fuel consumption and emissions to a minimum.

The heat range of these spark plugs is wider than ordinary plugs, offering more resistance to fouling and a higher pre-ignition rating. The secret to NGK's Wide Heat Range is the use of copper wire instead of the iron core in conventional plugs, allowing for superior heat conductivity to dissipate heat quicker. This prevents hot spots that could cause pre-ignition and ensures increased heat resistance without affecting fouling resistance.

These spark plugs are designed to maintain a sufficiently high temperature at the insulator nose to burn off carbon and oil deposits, while also allowing for a faster transfer of heat to the cylinder head to prevent overheating and premature failure. NGK engineers make specific heat range recommendations for each engine and the use to which it is put, ensuring optimum performance.

All global motorcycle manufacturers use NGK products in their motorcycles, demonstrating the quality and reliability of NGK spark plugs. With the exception of a couple of older applications, all the spark plugs in this motorcycle catalogue employ copper core technology, making them a superior choice for motorcycle maintenance. Whether you're a motorcycle enthusiast, a professional mechanic, or a motorcycle manufacturer, the NGK Spark Plug CPR8EA-9 is the ideal choice for optimal engine performance and longevity.
