NGK Spark Plug KR8DI Plugs [Box 4]

The NGK Spark Plug KR8DI is a high-quality and reliable spark plug designed to meet the demands of modern engines. With a focus on physical dimensions, combustion chamber shape, cooling abilities, fuel and ignition systems, these spark plugs are essential in optimizing engine performance while minimizing 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, ensuring maximum performance, economy, and value.

The heat range of the NGK Spark Plug KR8DI is carefully selected to dissipate heat effectively, with specific recommendations made for each engine and its intended use. This allows the spark plug to maintain a sufficiently high temperature at the insulator nose to burn off carbon and oil deposits or allow for faster heat transfer to the cylinder head, preventing overheating and premature failure.

Featuring NGK's Wide Heat Range, these spark plugs are suitable for both high-speed and low-speed driving, making them ideal for various driving conditions. With superior heat conductivity thanks to the use of copper wire, the NGK Spark Plug KR8DI effectively dissipates heat, prevents hot spots that could cause pre-ignition, and maintains resistance to fouling.

NGK's commitment to utilizing the latest production technology ensures that every aspect is catered for, providing exceptional performance, economy, and value. Whether it's for high-performance engines or everyday vehicles, the NGK Spark Plug KR8DI is the reliable choice to optimize engine performance and reliability.
