NGK IZFR6F11 Laser Iridium Spark Plug – Stock 4095
The NGK IZFR6F11 is a Laser Iridium spark plug designed for strong ignition, stable idle, and long service life. It uses a fine iridium centre electrode and a platinum-tipped ground electrode. This needs less voltage to spark and resists wear, so performance stays consistent over time.
This plug is pre-gapped to 1.1 mm and features a projected tip for efficient combustion. It has a gasket seat and a 16 mm hex, making installation straightforward with the correct socket.
- Sharper spark and smooth cold starts
