530Li N52B30 Replacement spark plug

August 17, 2024

Recently, the vibration of the engine after ignition is more obvious than before, and there is a feeling of jumping when accelerating rapidly. Because the usage rate of this car has not been high, the mileage traveled is only 41000 kilometers, and it has been maintained in a 4S shop, with an average of 6000 kilometers. Intuitive judgment that it is not a variety of rubber aging problems, then just replace the spark plug directly.
There was no class in the morning one day, so I made an appointment with the store in advance. We drove directly from the West Fifth Ring Road to the shops in the East Fifth Ring Road early in the morning to replace them. BMW’s 4S maintenance price is actually very real, especially after the car gets old, and the “Changyue” car over 7 years old is directly 30% off. The price of six NGK spark plugs for the N52B30 engine is 851 yuan, with a discount of 595.7 yuan and made in Japan. Don’t be deceived by the “50% discount price for 4S shops” in outside workshops. Don’t worry, the level of workers working for you is estimated to be 10% of the workers in 4S shops.
