NGK ILTR5K13 Laser Iridium Spark Plug
The NGK ILTR5K13 is a high quality Laser Iridium spark plug designed for reliable ignition and long service life. It delivers a strong, consistent spark that helps cold starts, smooth idle, and clean combustion. The fine iridium tip reduces the voltage needed to fire, which improves ignition stability under load and at high RPM. A platinum ground pad reduces wear and keeps performance steady over time.
Use this plug as a like-for-like replacement where specified. It keeps the correct heat range and characteristics the engine was designed for. This supports dependable performance on standard and tuned engines without increasing maintenance.
Do not change the heat range unless you know your engine needs it. Avoid forcing the gap on iridium tips.
