Breaking Down the Features of NGK Spark Plugs 2420/3000.6636 2420 Spark Plug – D9EA
Specifications
The NGK Spark Plugs 2420/3000.6636 2420 Spark Plug – D9EA boasts several key specifications that contribute to its performance and reliability:
- Thread Size: 12mm – This is a common thread size for many motorcycles, ATVs, and small engines.
- Reach: 19mm (3/4″) – This ensures the spark plug electrode is positioned correctly within the combustion chamber for optimal ignition.
- Hex Size: 18mm (11/16″) – A standard size for easy installation and removal with common tools.
- Gap: 0.035″ (0.9mm) – Proper gap is crucial for efficient spark and combustion.
- Resistor: Yes – The resistor helps reduce radio frequency interference (RFI) and protects sensitive electronic components.
- Heat Range: 9 – This indicates the plug’s ability to dissipate heat; a higher number means a “colder” plug, suitable for high-performance engines.
- Construction: Solid copper core and nickel tipped electrode – These materials provide excellent conductivity, heat resistance, and durability.
These specifications matter because they directly impact the spark plug’s ability to ignite the air-fuel mixture efficiently, withstand high temperatures and pressures, and provide a long service life. The solid copper core, for example, ensures excellent heat transfer, preventing the plug from overheating and causing pre-ignition or detonation. The nickel-tipped electrode resists wear and corrosion, ensuring consistent spark quality over time.
