For the 2014 Mazda6, there are two air filters: the engine air filter in the engine bay air box and the cabin air filter behind the glove box on the passenger side.
The engine air filter protects the intake system from dust and debris, while the cabin air filter helps keep interior air clean by filtering pollen, dust, and other particulates. Access to both filters is straightforward, but the locations differ: the engine filter is in the engine bay, and the cabin filter is behind the glove box. The following sections provide location details and practical steps for replacement.
Engine air filter location
To locate and replace the engine air filter, follow these steps:
- Park on a flat surface, turn off the engine, and open the hood. Locate the rectangular black plastic air box on the engine bay, usually on the driver’s side near the front and connected to a large intake hose.
- Unclip or unscrew the lid of the air box. There are typically 2–4 clips or screws along the edge; release them and lift the lid off.
- Remove the old filter cartridge from the housing and inspect the inside of the box for debris. If needed, clean the box lightly with a damp cloth or vacuum.
- Install the new filter in the same orientation as the old one, making sure it sits evenly and seals around the edges.
- Replace the air box lid and secure all clips or screws. Reconnect any hoses or clamps if you removed them, then close the hood.
- Dispose of the old filter properly and note the replacement interval in your maintenance records.
Regular replacement helps maintain engine performance and fuel efficiency. If you’re unsure about the exact interval, consult your owner's manual or a trusted Mazda service guide.
Cabin air filter location
To locate and replace the cabin air filter, follow these steps:
- Sit in the passenger seat and open the glove box. If your model uses a damper on the right side, gently detach or reposition it so the glove box can drop down.
- Look behind the glove box for a rectangular access door or panel that protects the cabin air filter. Remove the cover by sliding out or unclipping it.
- Take out the old cabin filter, noting the airflow direction indicated on the filter frame. Clean the housing area if you see dust or debris.
- Insert the new filter with the arrows pointing in the direction of airflow through the HVAC system (typically toward the rear of the vehicle). Ensure it sits flat and fully seated.
- Reattach the filter cover, re-seat the glove box damper if removed, and close the glove box. Ensure everything operates smoothly.
Replacing the cabin filter can improve interior air quality, reduce odors, and help with allergy symptoms. Check the maintenance schedule for recommended replacement intervals, which can vary by driving conditions and environment.
Maintenance tips and notes
- If your Mazda6 experiences reduced engine performance or unusual cabin odors, inspect both filters for excessive dirt or blockages and replace as needed.
- Always use the correct filter type and orientation as specified by Mazda for your exact trim and engine. When in doubt, refer to the owner's manual or contact a Mazda-certified technician.
Summary
The 2014 Mazda6 has two air filters: an engine air filter located in the engine bay air box on the driver’s side, and a cabin air filter located behind the glove box on the passenger side. Both are accessible with common hand tools or without specialized equipment, and replacement generally aligns with routine maintenance schedules or when performance or air quality declines. Following the step-by-step guidance above will help you locate, replace, and reset these filters effectively.
