NGK PFR6N-11 Laser Platinum Spark Plug (Stock No. 3546)
The NGK PFR6N-11 is a long-life Laser Platinum spark plug designed for stable ignition and reliable performance. It uses platinum on both the centre and ground electrodes to resist wear and keep the spark strong over a high mileage interval.
It helps cold starts, smooth idle, and consistent combustion in everyday driving. It also supports mild performance upgrades by keeping ignition steady under load. Use as a high-quality replacement where a heat range 6 plug and 1.1 mm gap are specified.
Always confirm fitment with the vehicle lookup or the Vehicle Fitment tab.
