NGK B6ES Spark Plug (Stock No. 7310)
The NGK B6ES is a dependable, non-resistor spark plug for many classic and older carburetted engines. It uses a copper core and nickel electrodes for stable spark, easy starting, and smooth idle. It is best suited to standard or mildly tuned engines that do not require a resistor plug.
- Consistent ignition for smoother running and reliable cold starts
- Non-resistor design for strong spark where suppression is not required
- Durable nickel electrodes with copper core for good heat control
