NGK BKR6EQUA Spark Plug – Quad Ground, M14 x 1.25, Heat Range 6
The NGK BKR6EQUA is a reliable, long-life spark plug for everyday road use and mild performance setups. It uses a projected tip and four ground electrodes to keep the spark consistent as the plug wears. This helps with smooth idling, clean starts, and steady performance over a wide mileage range.
Quad ground electrodes spread wear and resist fouling. A resistor core reduces electrical noise that can affect the ECU and infotainment systems. The standard NGK heat range 6 suits many mid-heat applications.
