What is the spark plug model for the Tayron 330?
3 Answers
The Tayron 330 has two types of spark plugs: DQ381 for the two-wheel drive version and DQ500 for the four-wheel drive version. The spark plug is a crucial component of the gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber, causing it to jump the electrode gap and generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. How spark plugs work: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block via the cylinder head. The insulator primarily serves to isolate the metal shell from the central electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the central electrode, it ionizes the medium between the central electrode and the ground electrode, producing a spark that ignites the air-fuel mixture in the cylinder. Spark plug replacement intervals: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the owner's manual. The following standards can be used as a reference for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.
I'm very familiar with Volkswagen spare parts. The 2.0T engine in the Tiguan L 330 typically uses NGK ILZKBR7B8DS spark plugs. This model is specifically designed for the EA888 engine, with a heat range of 7 that perfectly matches the turbocharging system, ensuring precise ignition to prevent carbon buildup and increased fuel consumption. I recommend owners check them every 60,000 km. Worn spark plugs can cause starting difficulties or engine vibration. When replacing them yourself, remember to disconnect the battery first and use a professional socket to gently unscrew them to avoid damaging the wiring harness. The new car manual will have the specific model reference, but confirm your vehicle's production year as some post-2019 batches might have minor adjustments. Pay attention to performance changes during daily driving - unstable idle requires immediate inspection. Although spark plugs seem minor, proper maintenance can save you fuel costs.
I've driven the Tanyue 330 and replaced the spark plugs a few times using Bosch FR7KI332S, which worked quite well. The original manufacturer only recommends this one model. After replacement, the engine response became more sensitive, and the throttle felt much lighter. I remember the first replacement was done after 50,000 kilometers at a 4S shop, costing a few hundred yuan in total. Spark plugs degrade over time, leading to sluggish acceleration or idle vibration, so they should generally be checked every 3 to 4 years. You can buy the parts online yourself, but make sure to choose genuine ones and don't go for cheap alternatives. When replacing, pay attention to safety—turn off the engine and wait for it to cool down before operating, otherwise, burns or short circuits can be troublesome. This directly affects the driving experience, and regular replacement ensures smooth operation of the car.
