The high-performance air filter is not only capable of providing a slight increase in horsepower, but it can also improve the fuel economy of your vehicle. This is because these filters draw air from outside the engine compartment, where the air is colder. Unlike regular filters, they don't need to be changed every year; all you have to do is clean them approximately every two years. High flow air filters offer better airflow and filtration of the air entering the engine.
This means that your engine can get more air, and thus perform better. In fact, a high flow air filter can increase your horsepower by 3 to 5 HP and also increase your torque. At the same time, this can lead to higher fuel efficiency. Some of the more expensive units come with a cold air intake unit, which extracts air from outside the car instead of the hot air used inside the engine compartment.
Cold air is denser and therefore will burn better, thus improving your engine performance. Don't expect a bunch of extra ponies to suddenly appear when you hit the accelerator; the numbers are small and you probably won't feel the extra power. But if you do some basic tests, you'll find that yes, high-performance air filters actually produce more power. The air cleaner is what prevents debris and dirt from entering your car's engine through the intake manifold valves.
There is a variety to choose from, especially when it comes to sports or performance air filters for cars. These filters don't clog as quickly or as easily because they have a larger surface area, but they offer better airflow and better filtration of the air entering the engine. One problem that has been observed is that, due to increased air intake, high-performance filters can expose the engine to more debris and contaminants. Therefore, allowing more air in through the use of a less restrictive sports air filter will give your car the possibility to increase power.
In addition to ensuring that performance remains consistent, a good air filter will ensure that fuel economy stays low.Since the filter is the first part of the intake system, the amount of air allowed to enter the engine has a direct correlation with the amount of horsepower that the engine can potentially produce. A high-performance air filter can help improve airflow and maintain the ideal air-fuel ratio, while protecting the engine from harmful contaminants.
