NGK Spark Plug DR8HS Plugs [Box 10]

The NGK DR8HS spark plugs are designed to accommodate the increasing demands of modern engines. These spark plugs play a crucial role in maximizing engine power while minimizing fuel consumption and emissions. Changes in engine design and fueling systems have led to the adoption of special features at the 'firing end' of the spark plug, such as extra projected tips and increased spark gaps. The use of precious metals on the tips of the spark plug electrodes is not uncommon, especially on higher performance engines, to enhance ignition quality and service life. NGK's engineering departments work closely with engine and vehicle manufacturers to produce the ideal spark plug type for each application. Every aspect of performance, economy, and value is catered for through the use of the latest production technology.

The heat range of NGK spark plugs is wider than ordinary plugs, making them suitable for both high and low speed driving. The wide heat range makes them more resistant to fouling and pre-ignition compared to conventional plugs. NGK's 'heart of copper' technology, where copper wire is used in place of the iron core, allows for superior heat conductivity, dissipating heat quicker and preventing hot spots that could lead to pre-ignition.

The NGK DR8HS spark plugs are of the 'S' type, with copper cored center electrodes for a wide heat range. This design allows for the dissipation of combustion heat away from the firing end and the use of longer insulator noses to protect against fouling. NGK's continuous research and development efforts enable them to offer special spark plugs designed to deliver optimum performance under a wide range of conditions. Whether for city driving or fast motorway cruising, these spark plugs are engineered to meet the demands of modern engines and deliver exceptional performance and reliability.
