NGK BKR6EYA-11 Spark Plug – Stock No. 4073
This NGK nickel spark plug is built for reliable ignition and clean combustion. It uses a projected, resistor design with NGK’s V-grooved centre electrode to help the spark start easily and burn the mixture more efficiently. Expect smooth idle, consistent performance, and dependable cold starts in everyday use.
Ideal as an OE-quality service replacement. It suits engines specified for a 1.1 mm plug gap, gasket seat, and 14 mm thread.
- V-groove centre electrode for stable spark under load
- Resistor design to reduce electrical noise and protect ECU systems
- Projected tip for efficient flame kernel and good drivability
