NGK BP6ES Spark Plug – Stock No. 7811
The NGK BP6ES is a reliable, non-resistor spark plug for many classic petrol engines. It uses a projected tip to improve cold starting and throttle response. The standard nickel alloy electrode is durable and cost-effective for road use.
Expect consistent ignition, smooth idle, and stable performance when maintained and gapped to your engine’s spec. It is a popular choice for older carburetted engines and many classic Japanese and European petrol engines that use a 14 mm, gasket-seat, long-reach plug. Please use our vehicle lookup or check the Vehicle Fitment tab to confirm compatibility.
- Projected tip helps burn clean and resist fouling in everyday driving.
- Non-resistor type for simple ignition systems where R-type is not required.
