How often should spark plugs be replaced in Volkswagen cars?

[QuinnAnn]

Volkswagen's original spark plugs should generally be replaced every 20,000 to 30,000 kilometers under normal conditions. For iridium or platinum spark plugs, replacement can be extended to every 60,000 to 80,000 kilometers. The electrodes of spark plugs repeatedly generate sparks to ignite the air-fuel mixture in the cylinders, while other components of the ignition system produce precisely timed high-voltage electrical pulses, creating sparks and explosions that provide the energy required for engine power output. The Volkswagen Lavida measures 4,670 mm in length, 1,806 mm in width, and 1,474 mm in height, with a wheelbase of 2,688 mm. The Lavida features front-engine, front-wheel-drive configuration, with a MacPherson strut front suspension and a torsion beam rear suspension.
