2017 Ford Focus-St Air Filter in Braintree, MA

The 2017 Ford Focus engine air filter sits in the engine bay inside the airbox on the driver’s side.

This panel-style filter is housed in a rectangular airbox that feeds the intake; pop the clips or screws to access it. Keeping this filter clean helps your Focus breathe properly around Braintree’s mixed city and highway routes. If you prefer a technician to inspect the intake housing and seals at the same time, book a schedule service appointment.

The engine air filter cleans intake air for combustion, while the cabin air filter cleans HVAC air for passengers.

Under-hood, the engine filter protects the Focus’s intake tract and sensors from dust that can affect performance. Inside, the cabin filter helps trap pollen and fine particles so the air you breathe is cleaner. Keeping both fresh supports efficiency and comfort during daily drives around Braintree and greater Norfolk County.
