Does the spark plug affect the power? Can changing the spark plug increase the power?

The operating principle of the engine is that the combustible mixture burns in the cylinder and expands rapidly, thereby pushing the piston down to rotate the crankshaft to generate power. The ignition and combustion of gasoline engine mixture must rely on the spark plug to emit a powerful electric spark at the right time. Therefore, the quality of the spark plug directly affects the power of the car.

Can changing spark plugs increase power?

Due to cost factors, automobile manufacturers usually do not equip ordinary automobile engines with the best spark plugs, but ordinary spark plugs can also perform the most basic tasks. Generally speaking, replacing the original spark plug with a spark plug with high energy, high voltage and high stability can increase the power by 10%. The better spark plug is the double iridium spark plug. Both the center electrode and the side electrode contain the rare metal iridium, which has high stability and service life, but the corresponding price will be higher.

In fact, not only the spark plug affects the power, the quality of gasoline also affects the power of the car. If the quality of gasoline is not good, the output power after complete combustion will be relatively small, which will easily cause insufficient engine power. If you replace with better quality gasoline, you can also increase a lot of power. In addition to the simple way to increase the power by changing the spark plug to increase the power and changing to a better gasoline, there are also the following modification methods.

1. Reduce the air inlet temperature

The principle is that the density of cold air is greater, and more air and fuel can be mixed in with the same volume, so that the fuel can be burned more fully to obtain more energy output.

2. Upgrade the car computer system

Upgrading the computer system that controls the vehicle can better allocate the program memory occupied by each module of the vehicle and make the system smoother. For example, the distribution of intake valve opening and closing time, fuel-air mixing ratio, etc.
