NGK IFR5L11 (Stock No. 6502) Laser Iridium Spark Plug
The NGK IFR5L11 is a premium Laser Iridium spark plug designed for reliable ignition, smooth running, and long service life. Its fine-wire iridium centre electrode needs less voltage to spark, which helps cold starts and keeps performance consistent as the miles add up. A platinum pad on the ground electrode reduces wear, so the gap stays stable for longer.
Use this plug when you want OE-level durability with a crisp, efficient spark. It suits standard and lightly modified petrol engines where a heat range 5 plug with a 1.1 mm gap is specified.
