Can changing to a better spark plug really increase the power?
1. In fact, it does not increase power
The main function of the spark plug is to ignite the mixed gas in the cylinder. When the car is working normally, the power has nothing to do with the spark plug.
The power of a car is mainly determined by four main factors: intake volume, speed, mechanical efficiency and combustion process.
In other words, the power of a car is determined when it leaves the factory. Without modification, it is impossible to increase the power beyond the original level by just changing the spark plug.
2. Good spark plugs last longer
So why do you need to change the spark plugs?
When we change to a better spark plug, we are actually just changing to a spark plug with better electrode material. The difference is that the service life will be a little longer.
For example, the service life of nickel alloy spark plugs is about 20,000-30,000 kilometers; single platinum spark plugs are 40,000 kilometers; and iridium spark plugs are 80,000 kilometers.
The cars that really need good spark plugs are those with bad engine conditions. Some turbo cars need to have their spark plugs replaced every 20,000 kilometers because the spark plugs on turbo cars corrode faster than those on naturally aspirated cars.
3. Does not increase power, but can restore power
Some friends think: I changed the spark plugs to better ones, and then I felt that the power became stronger. What’s going on?
In fact, it is possible that the power has not become stronger by replacing the spark plugs, but that it has been restored to its original level.
Because the original spark plugs are getting older and older, the credit is not to the more powerful spark plugs, but to the new spark plugs. The old spark plugs have more or less carbon deposits, and the carbon deposit problem does affect the engine power.
Too rich a mixture, long-term idling of the engine without load, high calorific value, too much lubricating oil, etc., can easily cause carbon deposits to form on the spark plug insulator, leading to problems with ignition performance and reduced power.
In addition, after the spark plug ages, the electrode will wear and corrode, and the gap will become larger, which will cause poor ignition.
Conclusion
Therefore, no matter from which perspective, choosing a good spark plug is crucial. It can restore the power of your car to a better state and make your car run better.
