NGK B8ES Spark Plug – Stock No. 2411
The NGK B8ES is a cold-grade, long-reach spark plug for engines that run hot or at high rpm. It uses a copper core and a durable nickel alloy electrode for steady ignition and good heat control. Ideal for many classic motorcycles and small engines that specify a 14 mm, gasket-seat, 19 mm reach plug. Always match the heat range and fitment to your engine spec.
- Cold heat range for hard use and sustained high rpm
- Reliable starts and consistent spark under load
- Resists fouling when the engine is hot
- Non-resistor design for a strong signal at the plug
Check fitment: Common on many classic two-stroke and air-cooled bikes, plus some small engines. Use the vehicle lookup to confirm, or see the Vehicle Fitment tab.

For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
