What is the replacement interval for Nissan Qashqai's spark plugs?
2 Answers
The replacement interval for Nissan Qashqai's spark plugs is between 60,000 to 90,000 kilometers. The functions of spark plugs are: 1. To introduce the high-voltage electricity generated by the ignition coil into the engine cylinder; 2. To generate sparks between the spark plug electrode gaps to ignite the air-fuel mixture, ensuring normal engine operation. Taking the 2021 Qashqai as an example, its body dimensions are: length 4401mm, width 1837mm, height 1593mm, with a wheelbase of 2646mm and a fuel tank capacity of 57 liters. The 2021 Qashqai features a MacPherson strut front suspension and a multi-link independent rear suspension. It is equipped with a 2.0L naturally aspirated engine, delivering a maximum horsepower of 151PS, a maximum torque of 194Nm, and a maximum power output of 111kW, paired with a 7-speed continuously variable transmission.
I've been working in automotive repair for over a decade. The replacement interval for the Qashqai's spark plugs is typically determined by the owner's manual. Nissan's official recommendation is to replace them approximately every 60,000 to 100,000 kilometers, or every 5 to 6 years, depending on the type of spark plug. For example, standard copper plugs have a shorter lifespan and are prone to aging, while higher-end iridium or platinum plugs can last longer. Driving habits also play a significant role; frequent stop-and-go city driving can accelerate spark plug wear. Early inspection and replacement can save fuel costs and improve performance. I've seen many owners neglect this, resulting in engine shaking, increased noise, and higher fuel consumption. It's best to have the mechanic check them during routine maintenance—it doesn't cost much, but the peace of mind is invaluable.
