2017 Ford Focus-Rs Air Filter in Lakewood, CO

The 2017 Ford Focus RS engine air filter sits in the engine bay airbox, typically on the driver side ahead of the intake tube.

This location allows filtered air to reach the 2.3L turbocharged inline-4 efficiently while protecting the mass airflow sensor. Open the hood, locate the rectangular airbox, and release the fasteners to access the element. If you’d rather leave it to a pro, our Lakewood team can inspect and replace it using genuine Ford parts.

• Access via clips/screws on the airbox lid

The 2017 Ford Focus RS cabin air filter is typically behind or below the glove box in the HVAC intake area.

Access often requires lowering the glove box and removing a small access panel. The cabin filter traps dust and pollen before air reaches occupants, which is helpful around Denver’s high-pollen spring and dusty summer conditions. If you prefer professional service, we can replace it and verify HVAC airflow.

• Access via glove box area panel
• Improves interior air quality and defogging

The engine air filter protects the 2.3L turbo engines intake, while the cabin air filter cleans air entering the HVAC for passengers.

On the Focus RS, a clean engine filter supports turbo efficiency, throttle response, and fuel economy. The cabin filter targets dust, pollen, and odors for occupant comfort. Both serve different systems and maintenance schedules, so theyre inspected and replaced separately during service.

Common signs include reduced power, lower MPG, rough idle, weak HVAC airflow, and musty cabin odors.
