Warm air changes volume
Before anyone embarks on modifications to the intake, and therefore the installation of an air filter with better throughput, they should understand a few basic contexts. It’s good to realize that the engine we need for performance increase quarrel above all more air, in terms of quantity, not volume (literally, it is to provide the aggregate with more oxygen molecules). The problem is that the volume of air fluctuates a lot with how warm it is. Most gases, when heated, increase in volume quite dramatically.
In conjunction with sports air filters, this phenomenon is a bit of a pitfall. The first is the fact that the installation of a new filter sometimes takes place in a “where it fits” way. It is often in the space where it then flows air heated by the engine or even better by a turbocharger, so its temperature is much higher than the current air temperature. But, as we said in the introduction, the heated air has a larger volume. Therefore, in fact, less will go through the air filter.
It is best to suck on the outside
So it is ideal to suck in air from somewhere where it is not heated by anything, ie preferably from the outside. This may require higher costs due to hood modifications, so some tuners resort to trying to get the intake somewhere. behind the bumper. It’s not a mistake, but it’s important to realize that the closer it sucks to the road surface, the more dust and all sorts of clutter will get into it. If it is not possible to take the intake out or to some reasonable place, the separation of the filter from the warmer air under the hood is solved at least heat shield.
The quality of the filter itself is also a question. It is often over some air filters literally visible against the light, which of course is not ideal – dust will enter the engine, which will form an abrasive after contact with the oil. It is then only a matter of time before the cylinder walls and piston rings grind and the loss of compression begins to manifest itself.
