The advantages and disadvantages of car modified air intake

What do I need to pay attention to when modifying the intake?

  1. Filtration performance of air barrier

An air barrier is what we call an air filter. The air barrier, as the first vital inlet of the car's air intake, can filter out the dust and impurities falling into the air and ensure the purity of the air intake. In this process, the air barrier affects the intake while filtering the air. Here to remind friends, the key role of air barrier is to filter the air, do not choose poor quality intake barrier because of cheap. The air barrier of poor filtration ability is easy to affect the excessive intake of engine air. Therefore, the premise of replacing the style is to ensure the filter, and consider the relationship with the intake efficiency.


So how to choose a filter guaranteed, intake efficiency has improved products? The easiest way to do this is to buy a big brand that has years of experience in modifying intake systems. Although the price is quite expensive, but partners basically understand the truth of a penny, such as KN, ARC, AEM, BMC and so on. And most advocate buying street products. Although the competing products have better air intake effect, they also lose low speed torque due to the pursuit of maximum power, and may not be as durable as street products. Of course, if it's to cheat, that's a different story.

  2. Invisible temperature relationships


Because the air has the characteristic of preheating expansion, the higher the intake temperature, the lower the oxygen content in the same volume of air, and the engine combustion depends on oxygen. Therefore, it is necessary to ensure that the air temperature inhaled by the intake system is as low as possible. However, due to the cost and location of each component, there is still much room for improvement in the size and location of the air intakes of the bellows on the original model.


Therefore, modifications can also be made for this, such as choosing insulation materials, choosing a location away from high temperature (exhaust manifold), further improving the intake performance.

  3. The shape of the intake pipe also matters.


And the modified head exhaust principle is the same, in general, the more smooth the shape of the bellows, the more straight and thick the intake pipeline, the smoother the wall, the better the performance of the entire intake bellows, the greater the power at high speed. On the contrary, moderately extending the length and shape of the intake pipe is more conducive to low torque output.


Generally speaking, the smoother the surface of the bellows, the thicker the intake pipe in front of the bellows, the smaller the curvature, the smoother the tube wall, the better the performance of the entire intake pipe. The improvement of carbon fiber bellows can improve the dynamic performance relatively simply. The original air intake style needs to be good, of course the price is higher, and aluminum alloy bellows insulation performance is slightly worse than carbon fiber, but through reasonable design can achieve good results.


This is theoretical, of course, because every car is designed with different torque output characteristics. Unless it is a targeted design modification, direct theoretical changes to the shape and layout of the intake pipe will not necessarily improve the dynamic performance, or even have the opposite effect. In view of this, a point of air intake modification brand will also launch targeted design for specific models.
