FULL DESCRIPTION
NGK Spark Plug DPR9EA-9
This NGK Spark Plug, part number DPR9EA-9, is engineered for optimal performance and longevity in high-performance engines. Its design incorporates advanced materials and construction techniques to ensure reliable ignition and efficient combustion.
Key Features:
- Wide Heat Range: Utilizes a copper core for superior heat dissipation, effectively cooling the electrode and insulator tip. This prevents overheating and pre-ignition.
- Enhanced Pre-Ignition Resistance: Features a high-conduction copper core and a long nose insulator to raise the pre-ignition rating, crucial for demanding engine applications.
- Projected Tip: The projected insulator tip design enhances performance by providing a clearer path for the spark and improving combustion.
- Triple-Sealed and Copper-Cored: This construction ensures efficient heat removal and prevents interior leakage, contributing to a longer plug life and consistent performance.
- Corrugated Ribs: The ribbed insulator helps prevent flashover, maintaining a strong and consistent spark even under adverse conditions.
- Pure Alumina Silicate Insulator: Constructed from a highly pure ceramic insulator for exceptional strength and superior heat transfer capabilities.
- Resistor Type: Designed as a resistor plug for optimal radio frequency interference suppression.
- Sold Individually: Each spark plug is supplied as a single unit.
