Air filters are designed to trap tiny particles and contaminants in paper or synthetic fiber media. As the filter media becomes filled with dirt and debris, the engine must work harder and fuel consumption increases. However, when the filter is replaced with a clean one, the air mixes with the fuel more efficiently, resulting in higher MPG. One of the advantages of a high flow air filter is that it doesn't need to be changed as often as a regular filter; it only needs to be cleaned approximately every two years.
High flow air filters offer better airflow and filtration of the air entering the engine, which can lead to improved performance. In fact, a high flow air filter can increase your horsepower by 3 to 5 HP and also increase your torque. This can also result in greater fuel efficiency. Some of the more expensive units come with a cold air intake unit, which extracts air from outside the car instead of using hot air from inside the engine compartment.
Cold air is denser and therefore burns better, improving engine performance. It's important to remember that your vehicle requires clean air to operate properly and efficiently. An air filter ensures that the air and fluids entering the engine are free of debris. When performing routine maintenance on your vehicle, don't forget to check the air filter.
When replacing filters, be sure to use one designed for your make and model of car. K&N filters allow more air to enter the engine more easily than regular paper filters, so the fuel ratio increases slightly to cope with the extra air, thus adding power (HP) to the engine. They also come with a cold air intake unit, which feeds cold air to the engine chambers for more efficient combustion of fuel. Modifications such as headers, better air filters and the like allow an engine to move air more efficiently by reducing restrictions on the airflow path.
Replacing a dirty air filter will reduce emissions and increase energy production without costing you money. The K&N air filter offers several benefits, including better fuel efficiency, lower fuel costs, and higher performance.
