FULL DESCRIPTION
NGK Spark Plug DPR8EA-9
The NGK Spark Plug DPR8EA-9 is engineered for high-performance engines, featuring a wide heat range due to its copper core construction. Unlike many conventional plugs that use iron cores, the copper in this NGK plug dissipates heat more effectively, which helps to cool both the electrode and the insulator tip. This design also contributes to a raised pre-ignition rating, enhanced by the high-conduction copper and a long nose insulator.
Key Features:
- Wide heat range for optimal performance.
- Copper construction for superior heat dissipation.
- Cools the electrode and insulator tip effectively.
- Raised pre-ignition rating for improved reliability.
- Designed to meet the demands of high-performance engines.
- Sold individually.
Specifications:
- Heat Range: 8
- Thread Size: 12 mm
- Type: Resistor
- Weight: 0.12 lbs
