※ Must read before purchase ※

Our store's products have very high requirements for car model compatibility. To ensure that the product model can be used, we suggest that you contact online customer service to provide information about the car model and choose the recommended model for you. Thank you!

 

 

Product Purchase Notice

To accurately adapt to your car, before purchasing a spark plug, please contact online customer service to provide one of the following two methods to help you match the spark plug model.

1）Vehicle identification code

2）Basic vehicle information

Mainly including:

①  Engine model; ② Vehicle model number; ③ Manufacturing year and month; ④ Displacement.

 

3.Replacement instructions                       

An example of spark plugs not working effectively due to long-term use

After electrode consumption, it is difficult to spark and cannot start normally

Carbon accumulation, blackening, dissolution, pollution, etc. in the ignition part lead to abnormal combustion of the spark plug (early ignition)

① Good

Spark plugs in normal use

② Electrode consumption

The edge loss of the electrode becomes dull, making it difficult to ignite and easy to stall during driving

③ Smoked black

The current leaks out through the carbon deposits attached to the ignition part of the spark plug, causing stalling and deteriorating engine performance

④ Sedimentation

The combustion gas attached to the spark plug overheats, causing abnormal combustion (premature ignition)

The above situations ②, ③, and ③ require timely replacement of spark plugs

 

4.Recommended mileage for testing and replacing spark plugs   

automobile	Light duty vehicles	motorcycle
15,000-20,000km	7,000-10,000km	3,000-5,000km

 

According to the different materials and types of spark plugs, the recommended replacement mileage will also vary. At the same time, the service life of spark plugs will also vary depending on the driving conditions of the car, the quality of gasoline, and driving habits,

 

We suggest that you regularly check and replace spark plugs before the engine runs abnormally.

(Spark plug models and types are diverse, please match the applicable model for installation)

thread diameter	Installation torque
18mm	35~40N · m (3.5~4.0kgm)
14mm	25~30N · m (2.5~3.0kgm)
12mm	15~20N · m (1.5~2.0kgm)
10mm	10~12N · m (1.0~1.2kgm)
8mm	8~10N · m (0.8~1.0kgm)

 

The required installation torque varies depending on the diameter of the spark plug thread.

Reference:                                         

When there is no torque wrench, it can be installed according to the following schematic diagram

NGK spark plugs with sealing washers and thread diameters of 18mm and 14mm

Newly installed products rotate approximately 1/2-2/3 (180 ° -240 °)

Install old products and rotate about 1/12 (30 °)

M18 and M14 have no special angles, they are both normal rotation angles. Please use the normal angles shown in the applicable table for installation.

NGK spark plug with sealing gasket and thread diameter of 12mm

All new products that have not been installed (except for M12 special angle models) rotate approximately 1/2 (180 °)

Installed old products (except for M12 special angle models) and rotated about 1/12 (30 °)

The installation method for M12 special angle models is that new products that have not been installed rotate about 1/4 (90 °), while old products that have been installed rotate about 1/8 (45 °)

NGK spark plug with sealing gasket and thread diameter of 10mm

All new products that have not been installed (except for M10 special angle models) rotate approximately 1/2 (180 °)

NGK spark plug with sealing gasket and thread diameter of 8mm

Newly installed products rotate by approximately 1/3 (120 °)

 

 

Note: It is very important to choose spark plugs with a heat value that is suitable for the engine and usage conditions.

When the calorific value is not suitable, the following phenomena usually occur.

Heating value and heat dissipation method of spark plugs

·Heating value too high

The temperature of the spark plug becomes too low, causing carbon buildup in the ignition part to cause electric leakage and prevent the spark from being ignited.

Low calorific value

The temperature of the spark plug rises too high, leading to abnormal combustion (early ignition), melting of the electrodes of the spark plug, and ultimately causing piston burnout, melting, and so on.

 

5.Performance improvement                      

Iridium platinum has superior ignition performance and longer service life, and the center electrode uses finer platinum/gold, which can provide stable idle speed; Superior resistance to dirt and damage; Quick start and acceleration; Improve fuel efficiency and reduce emissions.
