NGK Spark Plug DR8EIX Iridium Plugs [Box 4]

NGK's Iridium Plugs are designed to accommodate the increasing demands of modern engines. The spark plug design must consider various engine features like physical dimensions, combustion chamber shape, cooling abilities, fuel, and ignition systems. These plugs play a vital role in generating maximum power while reducing fuel consumption and emissions. NGK's engineering departments work closely with engine and vehicle manufacturers to produce the ideal spark plug type for each application.

The NGK Iridium Plugs utilize precious metal Iridium, allowing for an even smaller diameter center electrode without compromising durability. This small Iridium tip center electrode concentrates electrical energy, providing optimal performance in starting, idling, and throttle response. The taper-cut ground electrode further enhances performance.

Additionally, these spark plugs offer a wide heat range, making them suitable for both high speed and low speed driving. NGK's spark plugs have a higher pre-ignition rating compared to ordinary plugs with equal anti-fouling resistance. The use of copper wire instead of an iron core in conventional plugs contributes to the wide heat range, dissipating heat quicker and preventing hot spots that could lead to pre-ignition.

NGK's Iridium Plugs are designed to offer optimum performance under a wide range of conditions, making them a reliable choice for modern engines. With NGK's commitment to continuous research and development, these spark plugs provide durability and superior ignition qualities, making them an excellent choice for vehicle maintenance.
