How to replace Honda Accord 2015 air filter?

Replacing the air filter on a 2015 Honda Accord is a quick DIY job that takes about 5–15 minutes. With a fresh filter and a few basic tools, you can perform this maintenance yourself and help maintain engine efficiency and fuel economy.

What you’ll need

Before you begin, gather the necessary items and choose a compatible filter for your engine (2.4L four-cylinder or 3.5L V6). Using a quality OEM or aftermarket filter ensures proper fit and filtration.

• New air filter compatible with your 2015 Accord (2.4L or 3.5L engine)


• Basic hand tools or a screwdriver if the housing uses screws


• Clean rag or microfiber cloth


• Flashlight or work light (optional)


• Gloves (optional)

Having the right filter and tools on hand helps you complete the task quickly and reduces the chance of dropping debris into the intake.

Step-by-step replacement

Below are the practical steps you’ll follow. They apply to both engine options in the 2015 Accord. Adapt only if your model uses a different fastener arrangement on the air box.

1. Park on level ground, engage the parking brake, and turn off the engine. Allow the engine to cool for a few minutes to avoid burns.


2. Open the hood and locate the air filter housing. It’s the large black plastic box on the passenger side, connected to the intake duct that leads toward the front of the car.


3. Unclip or unscrew the air box cover. Some models use metal clips you can lift with your hands; others use small screws or bolts with a flat-head screwdriver or socket.


4. Lift the cover and remove the old air filter. Take note of the orientation (arrow on the filter typically points toward the engine).


5. Check the inside of the air box for debris. Wipe clean with a rag if needed, being careful not to push debris into the intake path.


6. Install the new filter, ensuring it seats firmly in the box with the correct orientation matching the arrows or molded guides.


7. Reinstall the air box cover and secure all clips or screws firmly but not overtightened. Reconnect any hose clamps that may have been disturbed.


8. With the air box sealed, start the engine and listen for any abnormal sounds or air leaks around the housing. A properly sealed box should run normally and quietly.

After completing the steps, dispose of the old filter according to local regulations and reset any maintenance reminders if applicable.

Engine variants and sensor notes

The general steps are the same for the 2015 Accord’s 2.4L four-cylinder and 3.5L V6. Some trims place the air intake closer to the radiator; if you need extra space, you can temporarily loosen the air duct clamp to move the pipe aside. The MAF sensor, if present on the intake tube, is typically not removed; if you do touch it, disconnect the electrical connector and handle the sensor per service guidelines.

Keep the air box fully sealed to prevent unmetered air from entering the engine. Avoid forcing the filter into a misaligned position to prevent leaks and engine misfires.

Maintenance tips

Regularly check the air filter’s condition and replace it when it becomes dirty or at the manufacturer’s recommended interval. In normal conditions, replacement every 15,000–30,000 miles is common; in dusty or harsh conditions, more frequent replacements are advised. Always refer to the owner's manual for exact intervals and filter part numbers.

Summary

Replacing the air filter on a 2015 Honda Accord is a quick, low-cost maintenance task that anyone can perform with basic tools. By keeping the filter clean and properly oriented, you help preserve engine efficiency, fuel economy, and overall performance. Always use a quality filter and reseal the air box securely after replacement.
