The air filter – a small part with a huge impact. It’s often overlooked during vehicle maintenance, yet it plays a crucial role in your engine’s performance and longevity. But what exactly is an air filter, and why is it so important?
Similar to how our lungs need oxygen to function, internal combustion engines require it too. This oxygen is supplied to the engine along with the incoming air. However, the air isn’t clean; it contains dust, dirt particles, pollen, and other contaminants. This is where the air filter plays its part: It filters these harmful substances from the air before they can enter the engine.
A clogged air filter can no longer perform efficiently. The result: The engine receives less oxygen, leading to a drop in performance, increased fuel consumption, and in the worst-case scenario, even engine damage. Imagine trying to breathe through a straw – it’s a struggle, isn’t it? Your engine feels similarly restricted with a dirty air filter.
“Regularly changing your air filter is essential for engine longevity and can help you avoid expensive repairs,” says Dr. Ing. Markus Schmidt, an automotive expert and author of the book “Modern Engine Technology”.
So, how often should you change your air filter? Experts recommend replacement every 9,000 to 18,000 miles (15,000 to 30,000 kilometers) or at least once a year. If you frequently drive on dusty roads, you might need to change it sooner.
Replacing the air filter is typically a straightforward task and can often be done by DIYers. You’ll usually find instructions on how to change the air filter in your vehicle’s owner’s manual.
Besides standard air filters, there are also ‘performance’ or ‘sport’ air filters. These claim to offer higher airflow, potentially leading to increased engine performance.
