Taking the 2020 Mazda 3 as an example, it belongs to the compact car category, with body dimensions of: length 4662mm, width 1797mm, height 1445mm, wheelbase of 2726mm, and a fuel tank capacity of 50l.

I've been driving a 3 for several years, and changing the air filter is super easy and hassle-free. It only takes a few minutes to do it myself. Here are the steps: Open the hood, and you'll see a black rectangular box on the left side of the engine—that's the filter housing. There are a few plastic clips on top; carefully pry them open with your hands or a flathead screwdriver. After removing the cover, take out the old filter—it might be covered in dust and grime, so remember to wear gloves to keep your hands clean. When buying a new filter, make sure to choose the correct model. Before inserting it, check the inner walls of the housing for dust and wipe them down if needed. Then place the new filter in evenly, ensuring there are no gaps around the edges. Finally, put the cover back on and press the clips firmly. Start the engine to listen for any unusual noises. I change mine every 20,000 kilometers, roughly once a year. A standard filter costs only about 20 yuan, which is much cheaper than going to a shop, and it helps extend the engine's lifespan. Over time, you'll realize these small tasks can save you a lot of money and prevent power issues caused by insufficient airflow.

Replacing the air filter for a Mazda3 is a straightforward task, perfect for beginners. Open the engine hood and locate the plastic box near the front of the engine, usually secured with clips that can be easily opened without tools. Remove the old filter and discard it, then wipe the inside of the box clean to avoid any residue. Align the new filter in the original direction—there's an arrow on the box indicating the airflow intake side to prevent incorrect installation. Press the edges gently to seal it properly before closing and securing the lid. The whole process takes less than 5 minutes, with the key being selecting the correct filter size—OEM or compatible products are recommended. Regular replacement every 15,000 kilometers can significantly improve fuel efficiency and reduce emissions. Forgetting to replace it may lead to increased engine noise, affecting the driving experience. Routine like this is something you can handle yourself, saving time and being practical.

Key considerations include choosing genuine filter brands, inspecting and replacing every 12,000 kilometers to prevent clogging, and avoiding operation in humid environments to prevent rust.
