NGK PFR6G-11 Platinum Spark Plug – Stock No. 5555
The NGK PFR6G-11 is a fine-wire platinum spark plug designed for clean, reliable ignition. It helps the engine start easily, idle smoothly, and burn fuel more completely. Platinum lasts longer than standard nickel plugs, so service intervals are usually extended.
The fine-wire centre electrode needs less voltage to spark. This improves ignition stability under load and at higher RPM. It can also help reduce misfires and maintain performance over time.
Use this plug if your vehicle specifies PFR6G-11. It is a resistor type plug, which helps reduce electrical noise that can affect sensors and the radio.
- Smooth cold starts and steady idle
- Durable platinum design for long life
- Consistent spark under everyday and spirited driving
