NGK BKUR5ET Spark Plug – Triple Ground (Stock No. 2789)
This NGK spark plug is a robust, long-life option for everyday road use. It uses a triple ground electrode to keep the spark strong and consistent over time. The U-groove design helps ignite the air-fuel mix more easily, which supports smooth idle and clean response. A built-in resistor cuts electrical noise that can affect the radio or ECU.
Expect reliable cold starts, steady running, and dependable performance. It is a durable nickel plug, not a racing or iridium upgrade, but a solid, OEM-style choice for regular servicing.
- Triple ground electrodes for stable spark and extended service life
- U-groove ground for better ignitability and cleaner combustion
- Resistor type to reduce interference with vehicle electronics
