ea211 ispublicThe engine of the brand model,Jetta, Polo,Lavida,SagitarAnd so on models are equipped with this engine. The spark plug of the ea211 engine is of the BOSCH brand. According to the recommendation of the Volkswagen manufacturer, the replacement cycle of the ea211 spark plug should be replaced every five thousand kilometers, and every major maintenance must be checked.
In addition, car owners are also more concerned about how much it costs to change a spark plug. The price of a single Bosch spark plug is about 70-80Yuan, The price of a group of four is about 240 yuan. If it is replaced in a 4s shop, the unit price of a spark plug is between 100-150 yuan. The price of the spark plug itself is not high, which means that the working hours are more expensive. The specific price is subject to the charging standards of the car 4S shops in various places.
Obviously, if you replace the ea211 spark plug according to the replacement cycle given by the manufacturer, the cost will be quite high. In fact, the service life of spark plugs is far greater than 15,000 kilometers. Even in a Jetta taxi that runs all the year round, the service life of their spark plugs can reach 100,000 kilometers. However, it is no problem for ordinary family cars to use 150,000 kilometers. of. Therefore, the replacement period of the ea211 spark plug can be determined according to the actual use of the spark plug. If the following situations occur, the spark plug needs to be replaced:
1. The center electrode of the spark plug is burnt off;
2. The carbon deposit is very serious;
3. The ceramic insulator of the spark plug has traces of scorching and breakdown.
When the spark plug fails, the engine will show abnormal jitter, lack of power, etc., and the faulty spark plug can be found by unplugging the plug of the high voltage coil by the cylinder-by-cylinder elimination method. If one spark plug fails, even if the other spark plugs are still working, they are still in a state of imminent failure. If conditions permit, it is best to replace all the spark plugs at once.
The replacement of spark plugs is also very particular. Even if you do not choose the original brand of spark plugs, you must ensure that the specifications of the new spark plugs are consistent with the old spark plugs. Replacement of spark plugs that do not meet the specifications will seriously affect the normal operation of the engine, and even cause the spark plug to burst and cause the engine to be scrapped.
Generally speaking, the specification of the spark plug refers to the size and calorific value of the spark plug. The size can be understood as the length of the new spark plug is the same as the length of the original spark plug, and the calorific value is the performance of the spark plug's heat dissipation and heat absorption capabilities. For car owners who do not understand spark plugs, when purchasing spark plugs, you can choose according to the text on the insulator of the old spark plug, and just choose the same text.
