How often should the spark plugs be replaced on a Volkswagen Lavida?

[McLaura]

Volkswagen Lavida spark plugs should be replaced every 40,000 to 60,000 kilometers. The working principle of spark plugs is to introduce the pulsed high-voltage electricity generated by the ignition coil into the combustion chamber, using the electric spark produced by the electrodes to ignite the air-fuel mixture and complete combustion. The Volkswagen Lavida is a compact 4-door, 5-seater sedan with body dimensions of 4670mm in length, 1806mm in width, 1474mm in height, and a wheelbase of 2688mm. It is equipped with a 1.4T turbocharged engine and a 7-speed dual-clutch transmission, delivering a maximum power of 110 kW and a maximum torque of 250 Nm. The drivetrain is front-engine, front-wheel drive, with a MacPherson strut front suspension and a torsion beam rear suspension.
