The method for replacing the air filter element on a 307 is as follows: 1. Open the car's engine hood, loosen the screw of the brake fluid reservoir, and then remove the intake pipe head; 2. After removing the surface cover, you can see the air filter box, then unscrew the screws of the air filter box; 3. Loosen the fixing screws at the connection between the air filter box and the throttle interface; 4. Remove the connecting hose, then push the air filter box to the right while lifting it, and the air filter box can be taken out; 5. After removing the air filter box, unscrew the screws of the air filter element, and then you can replace it with a new one. The function of the air filter element is to filter out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder.

I always change the air filter for my 307 by myself, which feels convenient and cost-effective. The process is simple: first, park the car on level ground and turn off the engine, letting it cool for a few minutes for safety. Open the engine hood, and the air filter box is located on the left side of the engine bay, near the battery—it's a black plastic box. Open the box cover, which has clips or knobs; just unfasten them. Carefully remove the old filter, which might be covered in dust and bugs, so wearing gloves is advisable to avoid dirty hands. Clean the inside of the box with a small brush or cloth to remove dust. Insert the new filter in the correct direction, noting the arrow indicating airflow to avoid putting it in backward. Close the cover and secure it tightly. The whole process takes just a few minutes and doesn’t require special tools. I recommend changing it every 15,000 kilometers or once a year, especially in dusty areas, to prevent air impurities from entering the engine and affecting performance and fuel efficiency. Buying the filter yourself is cheaper—just match the 307 model—and online tutorials are very practical to follow.

The first time I changed the air filter for my 307, it was a complete mess. The car's throttle felt sluggish, and I realized the filter might be clogged. I checked online and found it's located under the hood. Upon opening it, I spotted the plastic box on the left. I tried pushing the clips and almost broke them, with dust flying everywhere. When installing the new filter, I put it in the wrong direction and had to pull it out and start over. It took me half an hour to finish. Now, I'm used to it, and it's much simpler: opening the engine cover takes just a few minutes, and the box clips release easily—no special tools needed. Just remember to ensure the engine is off and cooled for safety, and wear gloves to avoid dust. The filters are cheap; just buy genuine ones that match the 307 model. After changing it, the car runs smoother, almost like it's breathing easier. Handling such small tasks yourself saves the hassle of visiting a repair shop and gives you some hands-on practice.

Be careful not to make mistakes when replacing the air filter. I've done it several times on my 307: it's located in the plastic box on the left side of the engine compartment. Open and close the lid gently to avoid damaging the clips. Before inserting the filter, check the directional arrow mark—installing it backward will prevent the engine from drawing in air. It's safer to do this after turning off the engine, and use an old brush to clean off dust. Typically, replace it every 15,000 kilometers to protect the engine. Skipping this step can extend the car's lifespan.

The air filter plays a crucial role in filtering dirty air and protecting the engine. After replacing it on my 307, the throttle response became quicker, and it even saved me some fuel costs. The replacement steps are simple: open the engine hood, locate the filter box, open the cover, and place the new filter in the correct orientation. Regular maintenance to prevent carbon buildup can extend its lifespan.

Before replacing the 307 air filter, prepare the following: purchase a matching genuine filter. No special tools are needed, just wear gloves to keep clean. The operation is simple: open the engine hood to locate the filter, which is in a plastic box on the left side with a clip-on cover. Remove the old filter and clean any internal dust. When installing the new filter, ensure the directional arrow is correctly aligned. Close the cover properly—the whole process takes no more than ten minutes. After completion, engine efficiency improves, and the enhanced filtration function better protects key components.
