Are you wondering if an aftermarket K&N air filter can really make a difference in your car's performance? If so, you're not alone. While it's true that most people won't feel any extra power from using an aftermarket air filter in their standard engine, those who have modified their vehicle to increase power and torque may benefit from using one. The K&N air filters are designed with high-quality materials that allow for increased airflow while still providing efficient filtration. This allows you to continue to get the performance you expect from your K&N intake system while also relying on its efficiency and cutting-edge protection. Most disposable paper filters restrict airflow significantly, since the openings of the filter material have to be extremely small to effectively filter, thus slowing down airflow.
The premium air filter included in a K&N intake system helps increase airflow by up to 50% compared to a traditional disposable paper air filter, and the intake tube is designed to flow a large volume of oxygen-rich air without the excessive baffles or components that slow down air flow that many factory systems have. On the test bench, aftermarket filters produce more than the OEM unit, and the K&N filter earns the most (about four horsepower and five pounds). In addition, Jason starts testing the dynamometer with a dirty air filter, an identical filter that is simply clean, a cheap alternative filter to the OEM and, finally, a K&N high-performance filter. A paper filter exhibits a principle called surface charge, since dust accumulates only on the surface of the filter medium. As dust accumulates on the surface of the disposable filter and blocks openings in the medium, the filter will normally restrict air flow more and more over time. What Fenske doesn't check is how well each aftermarket filter actually filters the air that enters the engine compared to the original unit.
As a result, K&N filters are capable of retaining significantly more dirt and particles per square inch of material than a normal paper filter. It suggests that the increase in power could be due to a smaller number of filters, especially in the case of the more economical CarQuest filter. If you've ever been to an auto parts store, you've probably seen air filter boxes that offer more power and torque than the factory ones. Yes, the K&N intakes protect the engine by using a specially designed, high-quality, high-flow air filter. The clean filter represented a marginal improvement over the dirty one, the cheap one was a marginal improvement over the clean OEM filter, although there would be a risk that this could be due to the fact that perhaps there is less material and, therefore, less real filtration and, finally, the K&N performance filter showed the best improvement, of almost eight horsepower, compared to the dirty filter and a 4.3 percent improvement over the cheap alternative filter. In conclusion, if you're looking for an aftermarket air filter that can help increase power and torque in your modified vehicle then you should consider investing in a K&N air filter.
The high-quality materials used in their design allow for increased airflow while still providing efficient filtration so you can continue to get optimal performance from your K&N intake system.
