NGK BKUR7ET Spark Plug – Triple Ground, Resistor, 14 mm Thread
The NGK BKUR7ET is a durable, OE-grade spark plug designed for reliable ignition in petrol engines. It uses a triple ground electrode to keep the spark consistent over a long service life. The U-groove ground design helps the flame start cleanly, even under higher loads. A built-in resistor cuts electrical noise that can affect the ECU and sensors.
This plug suits engines that specify a heat range 7 NGK plug with 14 mm thread and 19 mm reach. It is commonly found across many European petrol engines. Please use our vehicle lookup or check the Vehicle Fitment tab to confirm it fits your car.
Why it matters
– Stable spark and smooth running, especially on older or tuned engines.
– Multi-ground design resists wear, so the gap stays in spec for longer.
– Resistor construction reduces radio and ECU interference.
