Summary:
Changing your car’s air filter is a simple yet essential task to maintain engine performance and fuel efficiency. The engine filter prevents harmful debris from entering the engine, ensuring proper airflow and maintaining the correct air-to-fuel ratio. A clean filter improves acceleration, fuel economy, and engine longevity, while also reducing emissions.
Typically, you should replace the air filter every 12,000 to 15,000 miles. However, if you often drive in dusty conditions, you may need to replace it sooner. For instance, living in a suburban area with moderate dust, you might choose to replace it annually.
To change the air filter, you’ll need a screwdriver and a new filter compatible with your vehicle. First, turn off the engine, ensuring it’s cooled down, and open the hood. Consult your car’s manual or search online to locate the filter housing. Once found, unclip or unscrew the housing to remove the old filter. Discard the old filter and inspect the housing for any debris. Clean it if necessary.
Install the new filter, ensuring the pleats face the correct direction. Press the filter into place, then secure the housing and close the hood.
If you fail to change the air filter, the engine may struggle to start, fuel economy will drop, and engine performance will degrade. Signs that it’s time for a change include a lit engine light, decreased fuel efficiency, poor acceleration, unusual engine noise, or dark smoke from the exhaust. Regular filter maintenance ensures your engine stays healthy and performs optimally for longer.
