What material are the spark plugs used in the Volkswagen Lavida made of?
2 Answers
Volkswagen Lavida uses nickel-plated copper spark plugs. Spark plugs, commonly known as sparking plugs, function by discharging the pulsed high-voltage electricity delivered through the high-tension leads, breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. The Volkswagen Lavida is a sedan produced by Shanghai Volkswagen, which not only maintains the excellent quality of German design but also incorporates many aesthetic concepts reflecting traditional Chinese culture and cutting-edge design elements. The exterior dimensions of the Volkswagen Lavida are length 4670mm, 4541mm, and 4613mm; width 1806mm and 1765mm; height 1474mm, 1488mm, and 1460mm; with a wheelbase of 2688mm and 2610mm. The body structure is available as a 4-door, 5-seater sedan and a 5-door, 5-seater hatchback.
My Volkswagen Lavida has been running for several years, and I've always used iridium spark plugs—they feel really reliable. I remember when I first bought it, the 4S dealership recommended them, saying they're heat-resistant, have high ignition efficiency, resist carbon buildup, and protect the engine well. I've replaced them twice, with intervals of around 40,000 to 50,000 kilometers. It's simple to do it myself—just open it up and you can see the iridium tip design really enhances the spark, with noticeable fuel-saving effects and smooth throttle response. If I didn’t use the factory-recommended ones and switched to nickel alloy instead, they might be cheaper, but the durability is much worse—they’d need replacement every 20,000 to 30,000 kilometers. For maintenance, it’s best to stick with iridium plugs—don’t skimp on this small expense. The Lavida’s engine is well-matched, so long-term driving is hassle-free. Just check your spark plug specifications in the manual and you’ll see.
