Is it really useful to improve the gas, K&N high flow style？

Author: Long Wenzhe (please keep this paragraph for reprinting, or you will report the plagiarist) Cars, a complex industrial complex, have too much metaphysics. Even the OEM that knows the most about cars sometimes has to rely on it. With a fearless attitude, I’m going to talk to you today, an obscure warrior under the automobile metaphysics door. Air filter Also known as intake style.
The role played by the air filter is almost "the mask of the engine". First, it’s cheap, and second, it’s simple to fry chicken, so it naturally becomes one of the most basic upgrades.
As a result, a large number of post-market began to emerge, called High flow intake style Something. But up to now, there seems to be no scientific and correct statement to tell us whether this thing is useful or not. Eh, don’t panic ~ come with me. The main function of the air filter is to filter the air sucked in by the engine. As a "mask", some messy impurities and particles, such as Covid-19, are not allowed to run into the engine. Otherwise, it is easy to cause big problems. In addition to ensuring sufficient filterability, air resistance should not be added too much, and it should also be ensured that it can work for a long time without falling off the chain. This humble little thing is actually quite important. Everyone in the street likes to compare cars to people. If you want to run fast, you must be able to breathe in smoothly. Changing to the car means that the air intake should be big enough and cool enough. Then if I change to an air filter with large flow and low resistance, won’t the engine run faster and happier? It’s simple ~
This beautiful idea is established to some extent. However, to be clear, it is not rigorous to directly compare cars to people. Almost every part of the car has a scientific design and accurate calculation.
It’s not something that anyone can get the right answer by patting his head. Practice is the only criterion for testing truth. Now that we have reached the only standard, well, let’s look at a foreign talent. He used four different air filters and landed tests to tell you the conclusion.
Horsepower, measured 0-100km/h acceleration, both.

This little brother used four kinds of air filters, the original factory was dirty, the original factory was brand-new, the vice factory was brand-new, and the K prefix that everyone was familiar with was modified into an air filter.
The conclusions are as follows: The original factory is dirty: 158.25 horsepower, 01 acceleration 8.96 seconds. Original factory brand new: 160.10 horsepower, 01 acceleration 9.01 seconds. The auxiliary factory is brand-new: 163.32 horsepower, 01 acceleration of 8.91 seconds. Modified air filter: 164.42 horsepower, 01 acceleration 8.81 seconds. Yo-ho, this modified high-flow style seems to be really useful ~ at least in terms of dynamic parameters, there are changes. Although, not much.
But pinch, between data and experience, old drivers know that sometimes they are not necessarily equal, and the increase in horsepower figures does not mean that the car becomes easier to drive.
So Xiaobian rummaged through the whole network and read the messages, and found that the car owners who are using high-traffic style have several completely different voices. I probably summed it up:
1. There is no difference in driving and there is no change in fuel consumption;
2. There is no difference in driving, but the fuel consumption is reduced a little;
3. Driving is stronger, but the fuel consumption is also higher;
4. Drop the low twist, but the high speed is better; 5. The low twist is better, the rotation speed is faster, and the high speed is almost the same. What caused these differences in experience? What are the differences in the structure of air filter, which will make the engine have different performance?


And what is the high-flow style, IQ tax, chicken ribs, or cost performance? As a Civic owner who has used the K prefix to modify the air filter for more than three years, I estimate that I have more than 55,000 kilometers of real experience. What is the real face behind the high traffic? The next article will be interpreted for you.
