How Often Should the Spark Plugs on an Atenza Be Replaced?
2 Answers
Atenza spark plugs should be replaced every 120,000 kilometers. Spark plugs are crucial components of a gasoline engine's ignition system, responsible for introducing high-voltage electricity into the combustion chamber and generating sparks by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Signs that spark plugs are damaged include melted or eroded electrodes with rounded edges, as well as scarring, cracks, or carbon deposits on the insulator. Although the vehicle can still operate for a short period under these conditions, it is advisable to replace the spark plugs promptly. In terms of body dimensions, the Atenza measures 4870mm in length, 1840mm in width, and 1450mm in height, with a wheelbase of 2830mm.
I've been driving the Mazda Atenza for almost five years and found that the spark plug replacement cycle mainly depends on the car model and driving habits. The Mazda Atenza recommends checking the spark plugs every 40,000 to 60,000 kilometers. If you use high-grade iridium spark plugs, their lifespan may extend to 80,000 kilometers. Once, when I was driving on the highway, the engine shook noticeably. A diagnosis at the garage revealed that the spark plugs were worn, causing unstable ignition. After replacement, the smooth acceleration was immediately restored. City traffic conditions cause faster wear, while highway driving results in less wear. Regular replacement can prevent carbon buildup, avoiding a sudden increase in fuel consumption or stalling on the road. Usually, pay attention to whether the engine sound is steady at idle; if the color turns black, it should be addressed as soon as possible. Taking care of these small details can significantly extend the engine's lifespan.
