The engine air filter is housed in a rectangular black plastic box on the driver’s side of the engine bay (the left side when you’re seated in the car), near the front fender. It connects to the throttle body with a large intake hose, and is accessible by releasing the box’s fasteners to swap in a new filter.
Where to look in the engine bay
To locate the air filter housing quickly, follow the large-diameter plastic intake tube from the front grille toward the center of the engine. You’ll find a rectangular air-box secured with clips or screws, usually near the left wheel well. The mass air flow sensor sits along the intake tube just before the throttle body, which helps confirm you’ve found the right housing.
Visual cues to confirm the air box
Look for a sturdy black plastic box with a removable lid, multiple clips on the sides, and a thick hose connected to its side or top. The intake hose leading to the box is typically easy to spot, and the box sits low in the engine bay rather than up near the firewall.
Before attempting any maintenance, ensure the engine is cool and the hood is securely propped open. If your Accord is equipped with the 3.5L V6, the configuration is slightly different in shape but the air box location remains on the driver’s side for easy access.
How to replace the air filter
Replacing the air filter is a straightforward routine maintenance task. The following steps outline a typical process you can follow to swap in a new filter and reseal the housing.
- Unclip or unscrew the air box lid to open the housing.
- Remove the old air filter and inspect the inside of the box for debris or leaves; wipe the interior if needed.
- Check the new filter for the correct orientation; most filters have an arrow indicating airflow. Place the new filter into the box with the arrow pointing toward the throttle body.
- Reattach the air box lid and secure all clips or screws firmly.
- Reconnect any hoses or clamps you may have loosened, then start the engine to verify normal operation.
Keeping the air filter clean helps optimize fuel efficiency and engine performance. If you drive in dusty or harsh environments, you may replace the filter more often.
Additional considerations
If you’re unsure about the exact arrangement in your specific trim (2.4L four-cylinder or 3.5L V6), consult the owner's manual or a service guide for your 2014 Accord. The general location—driver’s side air-box near the fender with a large intake hose—applies to most models, but there can be small variations between engines and markets.
Summary
In a 2014 Honda Accord, the engine air filter sits in a rectangular plastic air-box on the driver’s side of the engine bay, connected to the throttle body by a large intake hose. Access it by releasing the box lid, replace the filter with the correct orientation, and resecure the lid. Regular replacement helps maintain performance and efficiency.
