How many kilometers should the Verna's spark plugs be replaced?
2 Answers
Verna's spark plugs should be replaced approximately every 40,000 kilometers. Spark plugs are essential components for the normal operation of the engine. After the air-fuel mixture is drawn into the cylinder and compressed, it must be ignited by the spark plug to complete the combustion process. Therefore, to some extent, the performance of the spark plug directly affects the ignition and combustion of the mixture. Due to factors such as the melting point and hardness of the electrode material, the electrodes gradually wear out. When the electrode gap becomes too large, the vehicle may experience issues such as reduced power, difficulty in cold starts, and increased fuel consumption. At this point, it is necessary to consider replacing the spark plugs. The Verna has a body length of 4340mm, a width of 1700mm, a height of 1460mm, and a wheelbase of 2570mm.
Over the years of driving the Karrina, I've found that spark plug replacement intervals typically fall around 40,000 kilometers. Standard nickel alloy spark plugs have a shorter lifespan and need replacement every 40,000 km, while premium iridium or platinum ones can last 60,000-80,000 km. Through long-term driving experience, I've noticed that timely replacements maintain the ignition system's efficiency, improving fuel economy and power output. Delaying replacement often leads to issues like hard starting, engine misfires, sluggish acceleration, and even increased overall fuel consumption. I recommend proactively asking technicians about spark plug condition during each maintenance service and deciding whether to replace them earlier or later based on actual wear. Though small, spark plugs play a crucial role in engine health - don't risk major problems by trying to save small money. Paying attention to these details helps keep your car running longer and smoother.
