two stroke scooter NGK Spark Plug BP6HS MAGNET Z8AC

By using a copper electrode, MEG have been able to produce a spark plug with a much wider efficient operating capacity. The plugs do not overheat under high operating loads and can therefore ignite fuel without burning their electrodes.
Ribs eliminate flashover.
New ceramic insulator provides better heat dissipation, higher electrical insulation and greater resistance against thermal shock.
More gaskets and special powder sealing prevent gas leakage and provide uniform heat range.
Copper electrode core deeply inserted inside the nickel tip greatly improves heat dissipation and prevents dangerous overheating.
Larger space between insulator nose and metal shell reduces fouling and misfiring keeps plug cleaner.
Thick, anti-corrosive nickel tip resists overheating and extends spark plug life.









Spark Plug Basics:
- The primary function of the spark plug is to ignite the air/fuel mixture within the combustion chamber under any operating condition.
- Spark plugs must provide a path and a location for electrical energy from the ignition coil to create a spark used to ignite the air-fuel mixture. A sufficient amount of voltage must be supplied by the ignition system to spark across the spark plug gap. This is called Electrical Performance.
- The spark plug firing end temperature must be kept low enough to prevent pre-ignition, but high enough to prevent fouling. This is called Thermal Performance and is determined by the heat range selected.
