NGK B7ES Spark Plug – NGK Stock No. 1111
The NGK B7ES is a non-resistor, gasket-seat spark plug designed for reliable ignition and stable performance. It uses a copper core for fast heat dissipation and a nickel alloy tip for durability. Heat range 7 in NGK terms makes it a slightly colder option than common road plugs, helping under higher loads or temperatures.
Why it matters
– Strong, consistent spark for smoother starting and idle
– Resists fouling better under sustained load due to colder heat range
– Robust construction for long service intervals when installed correctly
Fitment guidance
Suitable for many classic motorcycles, marine engines, karts, and older vehicles that specify NGK B7ES. Always confirm with the vehicle lookup or the Vehicle Fitment tab before ordering. Check your owner’s manual for the correct heat range and gap.
