Description
NGK PLZFR6A-11S Laser Platinum Spark Plug – Stock No. 5987
This NGK Laser Platinum spark plug is built for stable ignition, long life, and consistent performance. It uses a fine platinum centre electrode and a platinum pad on the ground strap to reduce wear and help maintain the correct spark gap over time. The projected tip helps cold starts and idle quality, while the resistor design cuts radio interference.
It suits many modern petrol engines that specify a 1.1 mm gapped platinum plug in NGK heat range 6. Commonly found in popular Nissan and Infiniti V6 applications. Use our vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details.
