A clean air filter allows your car to operate at optimal engine performance and fuel efficiency. And more than just improving performance, keeping your air filter clean can also prolong the lifespan of your engine. How often should you change your air filter? The answer depends on a few factors.
At Tillema Auto, we’re here to help you make sure your vehicle is in great shape so you can get where you need to go.
How Often Should I Change My Air Filter?
Under normal driving conditions, most manufacturers recommend replacing the engine air filter every 15,000 miles, or about once a year. However, this number can vary depending on a few factors, such as:
- Driving conditions. Dusty areas, gravel roads, heavy traffic, or frequent short trips may wear out your filter more quickly.
- Type of filter. Some filters will last longer than others. Reusable air filters understandably last much longer than disposable filters, but need regular cleanings.
- Vehicle make and model. High-performance vehicles often need filters with increased airflow.
Your owners manual will give you guidance on choosing the right filter. Or, just stop by Tillema Auto and we’ll make sure you have the best fit for your vehicle.
Why Is Changing the Engine Air Filter Important?
Your air filter’s job is to capture dirt and debris from the outside air and keep it from getting into your engine. A new, clean filter is great at doing its job. However, when it becomes too clogged with dirt, it limits airflow to the engine. This lack of airflow not only reduces the efficiency of the engine, but eventually can lead to more significant internal problems.
A damaged air filter can also be dangerous for your engine. Worse than just being clogged, an air filter that has more significant damage (such as rips or tears) can allow small dirt particles through to the engine, which can cause greater internal problems.
The cost of replacing your air filter is insignificant in light of the damage a dirty or torn filter can cause.
How Do I Know If My Engine Air Filter Needs Replacement?
A dirty air filter leads to decreased performance. It’s important to check your filter regularly to make sure it’s in good shape. Here are a few signs that your filter might need replacing.
- Poor acceleration or reduced horsepower
- Service engine light activation
- Black exhaust smoke
- Strong fuel smell
- Visible debris or discoloration when inspecting the filter
How to Check Your Engine Air Filter
If you want to check your air filter at home, here’s what to do:
- Locate the filter: Refer to your owner’s manual for its position (often in a rectangular box under the hood).
- Inspect visually: A clean filter is typically white or off-white. If it’s gray, dirty, or torn, replace it.
- Light test: Shine a flashlight through the filter. If light barely passes through, it’s clogged.
