How to Change Your Air Filter in 5 Simple Steps (in Just 5 Minutes)

Our Headlights writing team is always on the lookout for ways to help our readers learn new DIY tricks that make life easier and more efficient. Changing your car’s air filter is one of those simple tasks that can make a big difference. Here’s what you need to know:

• Your car’s air filter needs to be changed every 12,000 to 15,000 miles, or about once a year.
• If you drive in dusty conditions or frequently in stop-and-go traffic, you might need to replace it more often.
• A clean air filter improves engine performance and fuel efficiency, so replacing it regularly can save you money in the long run.

Step 1: Gather Your Supplies

Before you dive in, let’s grab what you need. The good news is, you don’t need much. Here’s the list:

• A new air filter (make sure it’s the right size for your car—check your owner’s manual or ask at your local auto store). You can easily find one at an auto parts store, like AutoZone or O’Reilly Auto Parts, or even order one online from Amazon for added convenience. Just make sure it matches your vehicle’s make and model.
• A screwdriver (usually Phillips or flathead, depending on your vehicle).
• Your hands (yes, that’s all you need for the real work).

Step 2: Find the Air Filter

This is where it gets easy. Locate the air filter box. It’s usually a black, rectangular box sitting near the engine. It might have a few clips or screws holding it in place—nothing too complicated. The location of the air filter box will vary by vehicle.

When I went to change the air filter in my Jeep Cherokee, I was surprised to find it located right under the passenger side. Who knew it was there the whole time? So, just make sure you double-check your owner’s manual or do a quick Google search with your car model—it’ll guide you straight to it.

Step 3: Remove the Old Filter

Now, the fun part! Use your screwdriver (or just your hands, depending on the design) to loosen the clips or screws holding the air filter cover in place. Once it’s off, carefully remove the old filter. You’ll probably see a bit (or a lot) of dirt or debris—no worries, that’s normal. Just don’t drop anything into the intake while you’re working, and keep it all clean.

Step 4: Insert the New Filter

Time to breathe fresh air again. Place the new air filter where the old one was, making sure it fits snugly and is properly aligned. If you have a reusable filter, give it a quick shake or brush to remove any dust before popping it in.

Step 5: Secure Everything

After the new filter is in, put the cover back on and tighten any clips or screws to make sure the air filters properly. You’re done! That’s it—five minutes, and your car is ready for some fresh airflow.

FAQs on How to Change Your Air Filter Yourself

Can a dirty air filter affect my car’s performance?

Yes, a dirty or clogged air filter can significantly impact your car’s performance. The air filter plays a crucial role in allowing clean air to flow into the engine for proper fuel combustion. When the filter is clogged with dirt, debris, or dust, it restricts airflow, which can lead to incomplete combustion. As a result, the engine may struggle to run efficiently, causing a decrease in fuel efficiency, a reduction in power, and rough idling.

Will a dirty air filter cause my check engine light to turn on?

A clogged air filter can contribute to poor engine performance, which may trigger the check engine light. If the filter is affecting the engine’s air-to-fuel ratio, the sensor may detect this issue and activate the warning light.

Can a dirty air filter cause my car to smell?

Yes, a dirty air filter can lead to unpleasant odors in your car. A clogged filter traps moisture and debris, which can mold or emit a musty smell into the cabin.

Does the type of air filter I use affect my car’s performance?

Yes, the type of air filter can influence your car’s performance. High-performance filters, such as those made from cotton or other premium materials, can provide better airflow and filtration compared to standard paper filters, offering improved power and efficiency.

One Simple Task, Big Benefits for Your Ride

Over time, the air filter gets clogged with the particles it’s meant to block, reducing your engine’s efficiency. This is where swapping out your air filter can make a big difference. By replacing the old filter, you’re helping your engine breathe easier, allowing clean air to flow freely.

The result? Improved fuel combustion, more power, smoother acceleration, and better fuel economy. So, don’t overthink it—next time you’re thinking about heading to the mechanic, why not save some cash and do it yourself?
