The 21 Bora 1.5 model was comfortable manually. It was 40,000 yuan. The spark plug had to be replaced. It just happened to catch up with the FAW-Volkswagen Jingdong 618 event to reduce 199 by 100. So I placed an order for L04c905626, 173.51. It was not enough to reduce the price, so I found a cheap air conditioner filter element to make up the order. Then the 4S shop started. After arriving at the store, there was no stock in the warehouse after the bill was issued. They said that the air conditioner filter element model was wrong, so this was easy to handle. They returned it, and the spark plug was also wrong. They said that the store only had 1.4T universal models and not 1.5 models. This was not easy to handle, with around 75 models. Isn’t this a rhythm that can’t be saved? Don’t worry about me. I have a backup plan. Previously, there was a coupon in another Jingdong account. It took a 612c model, which was expensive, about 266. This time, there is no need to make up the order. Pay directly at 166. The master had not finished changing the operating specifications yet. I didn’t take photos because I respected others. I removed the spark plug and went to eat. The cylinder tube was not protected. The 4S shop didn’t have insulating silicone grease. I said that I had to learn from it wherever I saw what I wanted to do. I could only laugh, and I didn’t use torque. It’s a long way to go! It’s no different from replacing it myself. I won’t go back after the insurance is out. I still apply silicone grease. The car was clean and didn’t wash it. In the end, I paid 64 yuan for working hours, and a total of 230 yuan was settled. It’s super cost-effective. I will do something else next time on the Double Eleven. By the way, are the 1.4T spark plugs compatible with the 1.5 spark plugs? Will it affect it? How many kilometers should I change it next time?
