NGK FR5CP Spark Plug – Stock No. 6368
A reliable OE-quality spark plug for smooth starts, clean combustion, and stable performance. The FR5CP uses a fine platinum centre tip for long life and consistent spark, with a copper core for good heat transfer. It suits many modern petrol engines that use a long-reach M14 plug. Always check your vehicle’s requirements in the Vehicle Fitment tab or use the site’s lookup to confirm.
