NGK SILZKR6B10E Laser Iridium Spark Plug – Stock No. 93815
This NGK Laser Iridium spark plug delivers reliable ignition and long service life. The fine iridium centre tip needs less voltage to spark, helping cold starts and stable idle. A platinum-tipped ground electrode resists wear, so the gap stays consistent for longer. Ideal for standard and lightly tuned petrol engines where consistent combustion matters.
Use this plug to maintain smooth running, reduce misfires, and support good fuel economy. It is factory-gapped and features a built-in resistor to reduce radio interference.
- Fine-wire iridium centre for strong, clean spark
- Platinum ground pad for long life and steady gap
- Resistor design to cut electrical noise
