NGK BP6ET Spark Plug – Stock No. 1263
A durable copper-core spark plug with a projected tip and triple ground electrodes. Designed for stable ignition, clean running, and long service life. Ideal for petrol engines that specify a non-resistor, 14 mm thread plug with 19 mm reach.
Use this plug to maintain reliable cold starts and consistent performance. The triple ground design helps the spark find a clean path as electrodes wear, which supports smoother idle and extended plug life.
Always confirm fitment using the vehicle lookup or the Vehicle Fitment tab. Only use if your engine calls for these exact specifications.
