NGK Spark Plug CPR6EA-9 Plugs [Box 10]

NGK Spark Plug CPR6EA-9 Plugs [Box 10] are designed to meet the increasing demands of modern engines, accommodating features such as physical dimensions, combustion chamber shape, cooling abilities, and fuel and ignition systems. These spark plugs play a vital role in maximizing engine power while minimizing fuel consumption and emissions. Additionally, they help vehicle manufacturers meet legislated emission targets and assist motorists in getting the best performance from their engines.

Due to increased space restrictions on some cylinder heads, NGK has adapted spark plug designs, such as taper seat and extended reach, to improve cooling of the inlet and exhaust valves. Some engines may require the use of two spark plugs per cylinder, each of different sizes. NGK also offers spark plugs with special features at the "firing end" to promote better combustion of the fuel/air mixture, especially in engines with modern fuelling systems.

To address the "cold fouling" effect in engines using unleaded fuels, NGK has developed spark plugs with specially arranged ground electrodes to burn away any built-up carbon, thus preventing poor starting or misfires. In addition, NGK utilizes precious metals on the tips of the spark plug electrodes for increased service life and superior ignition qualities.

NGK's engineering departments work closely with engine and vehicle manufacturers to produce the ideal spark plug type for each application, ensuring optimal performance, economy, and value. The spark plugs also have a wide heat range, making them suitable for both high-speed and low-speed driving conditions.

Furthermore, NGK spark plugs feature a heart of copper, providing superior heat conductivity to dissipate heat quicker and prevent hot spots that could cause pre-ignition. This copper core technology meets the broad thermal requirements of engines under high and low RPM conditions for maximum performance. With NGK Spark Plug CPR6EA-9 Plugs [Box 10], you can trust that your motorcycle's engine is receiving the highest quality spark plugs from one of the largest manufacturers in the world.
