Learn how an air filter affects engine performance and why it's important to replace it regularly.

How an Air Filter Impacts Engine Performance

The air filter in your car is an essential component that helps keep your engine running smoothly. It prevents dirt and debris from entering the engine, which can cause damage and reduce performance. When the air filter gets dirty, it can reduce the amount of clean air that reaches the engine, resulting in decreased power and acceleration. Replacing a dirty air filter with a new, clean one can help improve engine performance and extend the life of your engine.

The air-fuel balance of your car can be affected when a dirty or damaged air filter reduces airflow to the engine. Additionally, if the filter housing isn't closed properly, air that isn't properly filtered can enter the housing. It's important to get the right air filter for your car's make and model. If you let an air filter get too dirty, it will deprive the engine of air, which is necessary for efficient combustion.

Neglecting to replace your air filter can cause damage to your engine and lead to more expensive repairs. To avoid this, have your mechanic check your car's air filters every 12,000 to 15,000 miles or as recommended by the manufacturer. You may also notice some symptoms while driving that indicate it's time for an air filter change. Just like a cabin air filter keeps the interior of your car comfortable, an air filter at the engine intake is part of this protection for the engine.

A dirty air filter will reduce airflow to the engine and impair performance, including torque, power and acceleration. Even a particle as small as a grain of salt can pass through a damaged air filter and cause damage to internal engine parts such as cylinders and pistons. To maintain optimal performance of your car, it's recommended that you replace your air filters every 12,000 to 15,000 miles (19,000 to 24,000 km). Keeping up with regular maintenance makes it easy to stay on top of proper air filter changes.
