NGK Spark Plug CR9EHI-9 Plugs [Box 4]

Introducing the NGK Spark Plug CR9EHI-9 Plugs [Box 4], a top-quality spark plug designed to meet the ever-increasing demands of modern engines. NGK is a trusted manufacturer of spark plugs and lambda sensors, with a wide range of products used by global motorcycle manufacturers in their motorcycles.

The design of NGK spark plugs takes into consideration various engine features, such as physical dimensions, combustion chamber shape, cooling abilities, fuel, and ignition systems. These spark plugs play a crucial role in maximizing engine power while minimizing fuel consumption and emissions.

Due to advancements in engine technology, some cylinder heads have restricted space for spark plugs, leading to the need for spark plug design to adapt to these limitations. Some engines even require the use of two spark plugs per cylinder, with different sizes due to space restrictions.

NGK spark plugs also feature special design features at the 'firing end', such as extra projected tips that promote better combustion of the fuel/air mixture, which aids in improving economy. These spark plugs are engineered to dissipate heat efficiently and combat the 'cold fouling' effect that can occur with unleaded fuels.

The heat range of NGK spark plugs is wider than ordinary plugs, making them suitable for both high-speed and low-speed driving. These spark plugs have a higher pre-ignition rating and superior resistance to fouling.

One distinguishing feature of NGK spark plugs is the use of copper wire in place of the iron core, which provides superior heat conductivity and dissipates heat more effectively. This unique design ensures that NGK spark plugs meet the broad thermal requirements of engines under high and low RPM conditions.

NGK spark plugs are the result of close collaboration between NGK's engineering departments and engine and vehicle manufacturers, ensuring that the ideal spark plug type is produced for each application.

For reliable and high-performance spark plugs, look no further than the NGK Spark Plug CR9EHI-9 Plugs [Box 4] to keep your motorcycle running at its best.
