NGK BKUR6ET Spark Plug – Stock 6437
The NGK BKUR6ET is a reliable, resistor-type spark plug with a triple-ground electrode design. It delivers a consistent spark for smooth idle, clean combustion and steady performance. The three ground electrodes improve plug life and help maintain ignition quality over a longer service interval.
It suits many standard and lightly tuned petrol engines that use an NGK heat range 6 plug. The resistor reduces electrical noise that can affect the radio and ECU. The durable nickel centre electrode is built for everyday use with dependable cold starts.
- Triple-ground electrodes for longer service life and stable ignition
- Resistor type to reduce electrical interference
- Heat range 6 for balanced everyday performance
