NGK PFR7S8EG Laser Platinum Spark Plug (Stock No. 1675)
A high-quality, long-life spark plug designed for consistent ignition under daily driving and tuned use. The fine-wire platinum centre electrode needs less voltage to spark. This helps cold starts, smooth idle and reliable performance at higher loads. Suitable for many modern petrol engines that specify an NGK heat range 7 platinum plug. Use the vehicle lookup to confirm fitment or check the Vehicle Fitment tab.
