Let’s talk about the calorific value selection of spark plugs

Let's talk about the calorific value selection of the spark plug. The higher the calorific value of the spark plug, the stronger the heat dissipation. If the calorific value of the original car is 7, and you are used to riding in the red zone, you can only choose a spark plug with a calorific value of 8. , no matter how high it is, it is not appropriate. Don't blindly choose a spark plug with the same calorific value as a large displacement. It will only damage your car. It is safest to choose the spark plug model specified in the manual.
