Air filters play a vital role in the proper functioning of any internal combustion engine. Filtering out particulates from the air entering an engine helps maintain engine performance and protect it from premature wear. Over time, air filter elements can become saturated with debris and must be replaced to keep the engine running clean. This article will cover the basics of air filters and how their regular installation and replacement can help keep your engine in top condition for years to come.
The most common types of air filters used in automotive applications are paper filters and oiled cotton gauze filters. Paper filter elements are designed to trap fine particles in the air while allowing air to flow freely through its pleats. Oiled cotton gauze filters use a woven cotton material that is then treated with an oil to trap particles. These filters offer increased flow over paper filters, yet provide good filtration levels.
Due to the intake filter’s direct contact with the environment, it will inevitably become blocked by dust, dirt, and other debris over time. With this blockage, airflow becomes restricted, resulting in a diminished engine performance such as reduced fuel economy, slower acceleration, and engine stumbles. When the air filter element is regularly replaced, the engine will run more smoothly and efficiently.
In addition to replacing the factory filter, installing an aftermarket filter can add a boost of performance to any engine. Aftermarket filters are designed to offer improved flow over factory filters, allowing for more air to pass through the filter element. This combined with improved filtration levels can result in increased horsepower and torque, as well as improved fuel efficiency. An aftermarket air filter can also improve engine sound, providing a throatier engine note.
In conclusion, air filters play a critical role in maintaining engine performance and should be regularly inspected and replaced. Installing an aftermarket filter can offer increased performance over a factory filter and is a great way to add a bit of extra power to your vehicle. With proper maintenance, air filters can help your engine maintain peak performance for many miles of driving pleasure.
