How Often to Replace Car Engine Air Filter

Your car engine breathes in air to create energy that powers the engine. That air comes from outside, but it also breathes in dirty air from inside your car. Over time, this dirty air can build up on the engine’s filters and cause them to wear out or fail altogether. It’s important to keep your car’s filters clean and replaced as needed to ensure smooth operation and optimum fuel economy.

The Benefits of Regularly Replacing Your Car Engine Air Filter

According to the EPA, a properly functioning air filter can prevent up to 99% of harmful particles from entering your car’s engine. A dirty air filter can also cause reduced fuel economy and decreased performance. In addition, a clogged air filter can cause your car to stall or experience other engine problems.

To ensure optimal engine performance, consider replacing your car’s air filter every 7,500 miles. This will help to protect your car’s engine and improve its fuel economy.

It’s important to replace the filter regularly to maintain optimal performance and protect your vehicle.
