NGK BKR5EYA-11 Spark Plug – Stock No. 2526
This NGK V-Groove spark plug gives reliable ignition and smooth running. It uses a copper core with a nickel alloy tip for steady spark and good heat control. The V-cut ground electrode helps the flame start cleanly, improving cold starts and throttle response.
It is a resistor plug, so it reduces electrical noise that can affect the radio or ECU. Heat range 5 suits everyday road use in many naturally aspirated petrol engines.
