These car parts cost a lot of money and must be well protected

As we all know, a car is made up of thousands of parts. But do you know which parts are the most expensive among the thousands of them? We leave aside what the engine, car body, electronic system and transmission system, etc., these needless to say, must be the most expensive car parts, today we say the car which widget is the most expensive, the "most expensive" here how expensive is not necessarily the parts itself, but because these places often change or wrong probability is bigger, Large sums of money are spent on replacement and maintenance.

1, tire

The use of car tires is the highest frequency, different road conditions also make the tire is easy to damage, now many owners love explosion-proof tires, BMW every car is the use of explosion-proof tires. In the case of zero tire pressure can still drive a certain speed of one or two hundred kilometers, high safety factor, so the price is more expensive. We should pay attention to the maintenance of tires when using them.

2, the battery

No matter what kind of car battery is less than indispensable. Today we're talking about battery life and replacement cycles. The frequency of replacement also varies depending on the model and whether the battery is original or not. Now the car is generally replaced once every four years, which depends on the daily use and maintenance, generally in the start of difficult or can not drive the car can be replaced.

Since this is a consumable part, the price varies according to the model. The original will be slightly more expensive, while the non-original will be slightly cheaper. It should be noted that the cost of battery replacement is generally higher in the 4S or repair shop. It is suggested that the owners with strong hands can get it done by themselves.

3. Spark plugs

Under normal circumstances, the replacement cycle of spark plug is 30,000 kilometers, of course, the service life of different materials of spark plug is also different, nickel material spark plug, generally is to travel 30,000 kilometers after the change, do not insist on using. Platinum spark plugs must be replaced after 40, 000-50, 000 kilometers of driving, of course, if the wear and tear is significant, it should be replaced as soon as possible. Iridium spark plugs, made of a material that is resistant to wear and tear, are also safe and reliable when replaced after 100, 000 kilometres. Due to the large number of spark plugs, it is not just a replacement, a replacement of 4 or 6 is not a small number.

4. All kinds of filter elements

Air filter, oil filter, air conditioning filter, various filter elements, although the price is not very expensive, but the replacement frequency is a little more. Air filter is used when the engine is inhaled; The oil filter is the oil filter system; And air conditioning filter is air conditioning filter, which is directly related to the air quality of the car personnel breathing. Each is a frequently used component, so the frequency of replacement is high.

5. Electronic systems

Engine control, ABS, SRS(airbag), BCM(body computer, depending on the manufacturer's name), door module, IMMO (Immo), multimedia system, etc., no matter what module is damaged, it is relatively expensive, and many are also fragile, especially in the summer. If there is more rain water and improper drainage leads to the damage of electronic modules often occur.

No matter what parts, in use, we should pay attention to the daily maintenance to extend its service life. If we do not pay attention to the daily maintenance, the maintenance cost of the later period will accumulate over time. We should calculate an account to avoid the phenomenon of being able to afford but not able to afford.
