NGK LZKR6AI-10G Spark Plug (Stock No. 97999) This NGK spark plug delivers reliable ignition, stable idle, and clean combustion. It uses a fine-wire precious metal centre for a strong spark with less voltage, which helps cold starts and reduces misfires. It is a good choice for tuned petrol engines that need consistent spark under load, as well as standard cars that value long service life. Expect smoother running, better throttle response, and steady performance over a long interval. It is a resistor plug, so it helps cut electrical noise that can affect sensors and the radio.
