Description
NGK SILZKFR8F7S Laser Iridium Spark Plug (Stock No. 97566)
This NGK Laser Iridium plug delivers reliable ignition under hard use. The fine iridium tip needs less voltage to spark, which helps cold starts, smoother idle and consistent performance in turbocharged, high-compression engines. A platinum pad on the ground electrode improves durability, so performance stays stable over a long service life.
Use this plug as a high-quality OE replacement or when tightening up ignition performance on a lightly tuned car. It will not add power on its own, but it helps the engine make the most of the fuel and air you already have.
- Laser-welded iridium centre electrode for strong spark and long life
- Platinum-tipped ground for slower wear and stable gap
- Resistor design to reduce electrical noise that can affect sensors and the ECU
Always check and set the gap to your vehicle maker’s specification. Do not force iridium tips when gapping.
