NGK BKR6ETA-10 Spark Plug (Stock No. 7998)
This NGK spark plug is built for clean ignition, stable idle and reliable performance in everyday driving and mild performance use. It helps the engine start easily, burn fuel efficiently and keep emissions in check. The -10 suffix indicates a 1.0 mm factory gap for engines that require it.
Use this plug when your engine calls for a 14 mm thread, 19 mm reach, gasket seat plug in NGK heat range 6 with a resistor. It suits many modern petrol engines that specify this form factor, but always confirm using the vehicle lookup or the Vehicle Fitment tab.
Why it matters
– Strong spark for consistent combustion and smooth throttle response.
– Resistor design reduces electrical noise that can affect the ECU and sensors.
– Correct heat range helps manage plug temperature and reduce fouling or knock.
