To change the spark plugs, please ask which is better, BOSCH or NGK

NGK is better. NGK spark plugs.

It is mainly aimed at Japanese and Korean cars, while Bosch's spark plug products are mainly concentrated in European and American cars.

Japan's spark plug brand has been focusing on the development of spark plugs and has participated in many world competitions. In this behemoth, spark plugs are just one of the products.

Main advantages: Therefore, when purchasing a spark plug, you should pay more attention to the spark plug itself.

Here are some tips for buying spark plugs:

1. Check how many millimeters is the thread diameter of the spark plug used in your own model, and the current mainstream in China is 14 mm, so the standard and torque of the spark plug are generally tightened.

It was 25 30n m.

2. Check your own car engine.

The calorific value of the spark plug.

How much.

ngk。Relatively speaking, NGK spark plugs are mainly aimed at Japanese and Korean cars, while Bosch spark plug products are mainly concentrated in European and American cars. Both are also one of the most mainstream consumer-grade spark plug brands in the world, and the quality is comparable in civilian vehicles.

NGK uses a new type of ceramic alumina ceramic as an insulator. It has excellent insulation at high temperatures, and it really guarantees a spark. It has excellent thermal conductivity and can prevent excessive combustion.

It has strong resistance to thermal shock (quenching, quenching) and at the same time has high mechanical strength. It has a precise structure and excellent air tightness, and because it is connected to the main metal with a special powder, it has excellent air tightness and is also strong in structure.

Both brands have different grades, just choose according to your affordability. The lowest-grade nickel alloy is generally installed at the factory, then single platinum (that is, only the positive electrode is plated with platinum), then double platinum (that is, the positive and negative electrodes are platinum), then single iridium, and finally double iridium. The service life of various spark plugs is different, and the higher the grade, the longer the service life.

I don't know if there is anything more upscale.

NGK and Bosch spark plugsThere is no best difference between the two.

NGK specializes in the production of spark plugs, Bosch automotive home appliances are fully covered, spark plugs are one of the core consumables in car maintenance parts, and there is no best distinction between the two. The comparison between Bosch spark plugs and NGK spark plugs cannot give a good or bad conclusion, but Bosch is mainly a European banquet and a silver car, and NGK is mainly a Japanese and Korean car series, which has its own merits and quality.

In fact, the role of the spark plug is only ignition, as long as it meets the original calorific value and intermittent disgust, it is the best, the brand is nothing, as long as the best is the best. So it's hard to say which one is good and which one is bad, Bosch is suitable for American and German cars, and NGK Denso is suitable for Japanese and Korean cars.

Spark plug purchase proposal:

The function of the spark plug is simply to make the engine work by igniting the gas mixture in the engine. It's easy to say, but the role of the engine is still very important.

1. Check how much is the diameter of the external thread of the spark plug used in your own carmm, which is popular in China at this stage is 14mm, so the general specification of tightening the spark plug is 25 30nm.

2. Check how much heat is generated by the spark plug of your own car engine.

3. The raw materials of spark plugs are less harmful to the application itself, and the key difference is that the use period of Perkin spark plugs is longer, and the ignition response of iridium spark plugs is faster, and they are purchased according to the price they can receive.

ngkSpark plugsThe quality is very good.

The quality of NGK's spark plugs is very good, and NGK uses new ceramic high alumina ceramics as insulators.

It has excellent insulation at high temperatures, and it really guarantees a spark. It has excellent thermal conductivity and can prevent excessive combustion. It has strong resistance to thermal shock (quenching, quenching) and at the same time has high mechanical strength.

NGK is mainly made of spark plugs, and Bosch.

In addition to spark plugs, wipers, filters, electrical appliances, etc., although they are all big brands, NGK definitely has a great quality advantage and performance advantage in the field of spark plugs. NGK spark plugs are embedded with a copper core from the center electrode to the front end in order to dissipate a large amount of heat as soon as possible. As a result, it is resistant to burning and carbon deposits.

Precautions for the installation of fire mass slow flower plugs

Pay attention to the alignment of the thread, especially when the spark plug hole is deep, and special tools are required to lead or shi. If you feel a lot of resistance when screwing in, do not use force blindly, so as not to screw the threaded locust limb and cause damage. When tightening the spark plug, the tightening torque should be in accordance with the technical specifications, not too loose or too tight, so as not to leak air or damage the spark plug and spark plug hole.

The position of the spark plug is recessed, so the owner must clean the dust from the new spark plug, otherwise the dust will fall into the cylinder. A suitable socket wrench should be used.

Remove the spark plug. When using, the wrench should be placed so that the part other than the rubber ring of the wrench does not touch the tail of the spark plug, causing damage to the insulating porcelain.

Disassemble and assemble the spark plugs one by one. When the first spark plug is removed, a new cylinder spark plug should be installed to prevent foreign objects from entering the cylinder from the spark plug position. Once this happens, it will be very difficult.

When installing a new spark plug, a layer of lubricating oil can be applied to its surface, which can protect the cylinder head and make the next removal more effortless. Get a new spark plug, which can't be done all at once. In this way, the two electrodes of the spark plug may be stressed, and the gap distance will change, which will seriously affect the spark quality.

You have to put it in slowly, don't rush.

Relatively speaking, NGK spark plugs are mainly aimed at Japanese and Korean cars, while Bosch spark plug products are mainly concentrated in European and American cars. Both are also one of the most mainstream consumer-grade spark plug brands in the world, and the quality is comparable in civilian vehicles.

NGK, also known as Special Ceramics Co., Ltd., is a Japanese spark plug brand, which has been focusing on the development of spark plugs and has participated in many world competitions.

Bosch is a German industrial conglomerate, and spark plugs are just one of the products in this behemoth.

Therefore, when buying a spark plug, we should pay more attention to the spark plug itself, and the following are the suggestions for buying a spark plug:

1. Check how many millimeters is the thread diameter of the spark plug used in your own model, and the current mainstream in China is 14 mm, so the standard for tightening the spark plug is generally 25 30Nm.

2. Check what is the calorific value of the spark plug of your car engine.

3. The spark plug material has little impact on the use itself, the main difference is that the platinum spark plug has a longer service life, and the ignition response of the iridium spark plug is faster.
