NGK SPARK PLUG D9EA 2420

NGK Spark Plug D9EA - High-Performance Ignition

TheNGK D9EA Spark Plug is engineered for reliable ignition and optimal performance in motorcycles and small engines, particularly those operating under demanding conditions. Its advanced design focuses on efficient heat dissipation and consistent spark delivery.

Key Features:

• Copper Core Technology: Features a copper core that excels at dissipating heat, effectively cooling the electrode and insulator tip. This prevents overheating and significantly extends the plug's operational life.
• High-Performance Engine Ready: Built with a raised pre-ignition rating and high-conduction copper, this spark plug is robust enough to meet the thermal challenges of high-performance engines.
• Non-Resistor Design: This is a non-resistor type spark plug, making it ideal for applications where electrical interference suppression is not a primary concern.

Specifications:

• Heat Range: 9 (Suitable for engines that operate at higher temperatures).
• Thread Size: 12mm (A standard dimension for widespread compatibility).
• Gap: 0.028 inches (0.7mm) (Precisely set for optimal ignition).
• Hex Size: 11/16 inches (18mm) (Standard size for ease of installation).
• Reach: 19mm (Ensures proper seating in the cylinder head).
• Terminal Type: Stud Terminal Threads (Designed for secure threaded stud connections).
• Seal Type: Gasket Seat (Provides a tight and reliable seal).
• Resistor: No (Designed without a resistor for specific application needs).

Construction Benefits:

• Superior Heat Dissipation: The copper core actively draws heat away, maintaining cooler operating temperatures and enhancing plug durability.
• Extended Lifespan: NGK's construction methods promote greater strength and improved heat transfer, even under high-temperature operating environments.
• Stable Ignition Performance: The non-resistor design facilitates a consistent and strong spark, crucial for reliable ignition, especially in performance-oriented engines.
• Efficient Combustion: A precisely engineered gap and design contribute to a clean, powerful spark, leading to enhanced ignition efficiency and overall engine performance.
• Triple Seals: Integrated triple seals help prevent internal leakage and contribute to heat dissipation.
• Corrugated Ribs: These ribs are designed to prevent flashover, ensuring a stable spark and dependable engine operation.

This spark plug is a traditional design choice, well-suited for vintage motorcycles, high-performance engines, and any small engine requiring dependable spark performance under demanding conditions. It offers improved heat management, longer life, and stable operation for a variety of vehicle and equipment applications.
