NGK PFR6E-10 Laser Platinum Spark Plug – Stock No. 3688
This NGK Laser Platinum plug gives a clean, reliable spark for everyday use and light performance builds. The fine platinum centre and ground pads help the spark form easily, resist wear, and keep the gap stable for many miles. It starts well in cold weather, runs smoothly at idle, and holds up under motorway cruising and spirited driving.
- Strong, consistent ignition for smoother running and better throttle response
- Platinum tipped for long service life and stable gap
- Resistor design to reduce electrical noise that can affect sensors and the radio
Always confirm the correct heat range and factory gap for your engine. Use our vehicle lookup or check the Vehicle Fitment tab.
