How many kilometers should the Nissan Sylphy's spark plugs be replaced?

[JuliaDella]

Nissan Sylphy's spark plugs should be replaced every 60,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high-voltage electricity into the combustion chamber, causing it to jump across the electrode gap and generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. To some extent, the performance of the spark plugs directly affects the ignition and combustion of the mixture. The Sylphy is a compact sedan under Nissan, with dimensions of 4,641 mm in length, 1,815 mm in width, and 1,450 mm in height, and a wheelbase of 2,712 mm. In terms of power, the Sylphy is equipped with a 1.6-liter naturally aspirated engine across all models. This engine delivers a maximum power of 99 kW and a maximum torque of 159 Nm. It features EVTC technology and multi-point fuel injection, and utilizes an aluminum alloy cylinder head and block.
