FULL DESCRIPTION
NGK D8HA Spark Plug
The NGK D8HA Spark Plug is engineered for optimal performance and durability in a variety of engine applications. Featuring a robust copper core, this spark plug efficiently dissipates heat from the electrode and insulator tip, preventing overheating and extending the plug's lifespan. Its design includes a raised pre-ignition rating, achieved through high-conduction copper and a long nose insulator, which ensures superior heat distribution and reduces the likelihood of pre-ignition in demanding engines.
This is a non-resistor spark plug, making it suitable for engines that do not require electrical interference protection. The NGK D8HA is built with triple seals to prevent interior leakage and aid in heat dissipation, while corrugated ribs help prevent flashover for a stable and reliable spark.
