High-performance air filters are a great way to improve the performance of your car. Not only do they slightly increase your horsepower, but they also improve fuel economy by drawing in colder air from outside the engine compartment. This helps to prevent dirt, dust, and other debris from entering the engine and causing costly repairs. When looking for the best air filter for your car, you should consider one that offers high airflow and high particulate removal.
This will help to maintain maximum performance and reduce the hassle of regularly changing your air filter. Many aftermarket manufacturers sell engine intake air filters that they claim provide better airflow and increased power and acceleration. The benefits of a high flow air filter include not needing to be changed every year, as they don't clog as quickly or as easily. This can lead to higher fuel efficiency and an increase in horsepower of up to 5 HP.
Some of the more expensive units come with a cold air intake unit that extracts air from outside the car instead of the hot air used inside the engine compartment. However, it is recommended that you replace your air filters at least every 12,000 to 15,000 miles (19,000 to 24,000 km) to maintain maximum performance. A number of aftermarket manufacturers sell engine intake air filters that they claim provide better airflow and, as a result, increase a car's power and acceleration. In conclusion, high-performance air filters are worth it for your car if you want to increase power, fuel efficiency, or simply reduce the hassle of regularly changing your air filter.
They don't necessarily give you more power, but they are better at avoiding energy loss once you've driven a couple of thousand miles. Unless you're going to spend a lot of money on a cleanable K&N type filter, there is no real benefit of improved air filters.
