What you’ll need
Before you begin, gather these items to ensure a smooth replacement process.
- Replacement engine air filter that matches your engine (OEM or equivalent)
- Clean rag or microfiber cloth
- Gloves (optional)
- Flathead screwdriver or small pliers (if needed to release clips)
- Flashlight or phone light to inspect inside the air box
With the right parts and tools on hand, you’ll be ready to replace the filter efficiently and with minimal contamination.
Steps to replace the air filter
Follow these steps in order to replace the filter correctly and ensure a proper seal.
- Park on level ground, turn the engine off, and engage the parking brake. For safety, wait until the engine is cool before touching engine components.
- Open the hood and locate the air filter housing. On the 2017 Accord Sport, it is the large black plastic box on the passenger side of the engine bay, connected to the intake tube.
- Unclip or unscrew the air box lid to release it. There are typically several metal clips along the edge; some models use screws or fasteners that may require a screwdriver.
- Carefully lift the lid and remove the old filter. Note the orientation of the filter so you can install the new one the same way.
- Inspect the inside of the housing for dust or debris and wipe it clean with a rag if needed before inserting the new filter.
- Insert the new filter, ensuring the orientation matches the old filter and that the airflow arrow on the filter points toward the engine (direction of air flow).
- Re-seat the lid and re-clip or re-screw the fasteners. Reconnect any intake hose clamps if you loosened them during removal.
- Close the hood, start the engine, and listen for any unusual noises indicating a loose fit. The engine should run smoothly with improved intake air quality.
After replacing the filter, there’s no special reset required for the maintenance minder on most Accords; simply drive normally and monitor for any warning lights.
Maintenance and tips
Best practices and common pitfalls
To maximize filter life, check the air filter at routine service intervals and inspect it more often in dusty or dirty conditions. Replace promptly if the filter shows heavy dirt, damage, or collapse. Always verify the correct filter type and orientation for your engine variant (some 2017 Accord models use different engines; consult the owner's manual or parts listing if in doubt).

Replacing the engine air filter on a 2017 Honda Accord Sport is a straightforward DIY task that can boost performance and fuel efficiency. With the right filter, a few basic tools, and careful steps to avoid contamination, you can complete the job in under 20 minutes and keep the engine breathing clean air.
