Description
NGK LTR6DI-8 Double Iridium Spark Plug (Stock No. 96588)
This NGK double iridium spark plug delivers a clean, stable spark for reliable ignition and long life. The fine-wire iridium centre electrode needs less voltage to fire, which helps cold starts and smooth idle. It also resists wear, so performance stays consistent for longer service intervals.
The -8 gap (0.8 mm) suits many modern petrol engines running standard to mildly tuned setups. It is a good, all-round heat range for daily use with occasional spirited driving.
