The NGK CR7HS (Stock No. 7223) is a high-quality copper-cored spark plug designed for small-capacity motorcycle and scooter engines,
ensuring efficient heat dissipation and fouling resistance. It features
a 10mm thread diameter, resistor technology to reduce interference, and
is commonly used in Honda Cub and youth ATV models.
Key Features and Benefits
- Copper Core Electrode: Provides superior heat conductivity, preventing overheating and pre-ignition.
- Resistor Technology: The "R" in CR7HS denotes a built-in resistor, reducing electromagnetic interference.
- Fouling Resistance:
A longer insulator nose protects against fouling.
- Durable Design: Constructed with alumina silicate insulator for strength and a triple-gasket seal to prevent leakage.
- Anti-Flashover: Corrugated ribs on the insulator prevent spark flashover.
