NGK Spark Plug CR9EIA-9 Plugs Iridium [Box 4]

The NGK Spark Plug CR9EIA-9 is constructed with precision engineering and cutting-edge technology to provide maximum power and optimum performance for modern engines. The spark plug's design takes into consideration physical dimensions, combustion chamber shape, cooling abilities, fuel, and ignition systems, ensuring efficient combustion and reduced emissions. It features a special electrode arrangement to combat the 'cold fouling' effect that can occur in engines using unleaded fuels, allowing for superior ignition qualities.

NGK's engineering department works closely with vehicle manufacturers to produce the ideal spark plug type for each application, ensuring compatibility with a wide range of engine requirements and driving conditions. With a wide heat range, NGK spark plugs are suitable for both high-speed and low-speed driving, offering more resistance to fouling compared to ordinary plugs with equal anti-fouling resistance. The NGK Spark Plug CR9EIA-9 also features NGK's Heart of Copper technology, utilizing copper wire in place of the iron core in conventional plugs to provide superior heat conductivity and dissipate heat quickly. This prevents hot spots that could cause pre-ignition, ensuring peak performance under high and low RPM conditions.

In addition, the NGK Spark Plug CR9EIA-9 is designed with a heat range that indicates its ability to dissipate heat produced during combustion, with NGK engineers making specific recommendations for each engine to ensure optimum performance and prevent premature failure. With a wider heat range than ordinary plugs, the NGK Spark Plug CR9EIA-9 is ideal for engines that tend to run hot or cold, offering flexibility and high resistance to fouling. Choose NGK for reliable, durable, and high-performance spark plugs for your motorcycle or vehicle.
