Generally, large-displacement vehicles run at low idle speeds, while small-displacement vehicles run at high idle speeds for a longer time. Also, if you change the original spark plug, don’t change the calorific value of the spark plug. Change to high-performance spark plugs such as iridium and platinum to increase the calorific value as much as possible. If you don’t understand, you can consult our customer service online Q&A. There is also a choice of spark plug calorific value. One factor is the area where the vehicle is used. Generally, low-temperature and low-calorific value spark plugs should be used as much as possible in the cold northern areas. Of course, it would be better to use smart calorific value spark plugs. In the hot southern areas, try to use cold spark plugs. Choose cold spark plugs, and riders who drive in a proper way should try to use the original calorific value spark plugs. According to the experience of the spark plug house, the use of high-calorific value spark plugs will increase the response sensitivity under rapid acceleration at high speed, and the use of low-calorific value spark plugs will have good acceleration performance at low speeds, and the torque will increase, and the response will be sensitive.

In short, the correct selection of the calorific value of the spark plug will improve the power and sensitivity of the vehicle, increase the usability of the vehicle, and maximize the performance of the engine. Remarks: The heat value of the original spark plug is designed by the design engineer based on most people's usage habits and at room temperature. The above method of selecting spark plugs is used on the basis of replacing high-performance spark plugs. Drivers who use the original spark plug do not need to change the heat value of the spark plug. , Try to figure out the calorific value of the original spark plug before replacing it.
