2017 Ford Focus ST Air Filter in Draper, UT

The engine air filter on a 2017 Ford Focus ST is located in the engine bay inside the plastic intake/airbox assembly on the front side of the engine compartment.

On the 2017 Ford Focus ST you’ll find the intake box easily accessible from the top of the engine bay; it secures with clips or screws that allow quick access for inspection or replacement. Technicians at Larry H. Miller Ford Lincoln Draper will check the housing seals and the mass-airflow sensor when replacing the filter.

• Located in the plastic airbox in the engine bay
• Accessible from above; typically held by clips or screws
• Technician will inspect housing seals and MAF sensor

The cabin air filter on a 2017 Ford Focus ST is located behind the glove box inside the HVAC plenum.

Access usually requires lowering or partially removing the glove box to reach the filter cover. This placement protects the HVAC system from pollen, road dust, and debris, and is why LHM Ford Draper inspects the fit and seals when performing service in Draper’s seasonal pollen periods.

• Located behind the glove box within the HVAC plenum
• Glove box removal or lowering is commonly required for access
• Technician checks filter seating and cabin-side drain paths

The engine air filter filters combustion intake air for the 2017 Ford Focus ST’s turbocharged 2.0L engine, while the cabin air filter cleans air entering the passenger compartment through the HVAC system.

The engine filter protects the turbocharger, MAF sensor, and engine internals from particulate contamination; the cabin filter traps pollen, dust, and odors to protect passengers. Service in Draper should consider seasonal pollen and local dust when deciding replacement timing.

• Engine filter = protects engine intake and sensors
• Cabin filter = protects HVAC system and passenger air quality
• Both filters contribute to performance and comfort but serve different systems

Common signs of a clogged air filter on a 2017 Ford Focus ST include reduced engine power, decreased fuel economy, rough idle for the engine filter, and weak HVAC airflow or musty odors for the cabin filter.

If you notice sluggish acceleration or higher-than-normal fuel use while commuting on I‑15 or the frontage roads, the engine intake filter may be restricted. Inside the cabin, reduced vent airflow or persistent odors—especially during Draper’s high-pollen seasons—indicate the cabin filter needs inspection or replacement.

• Engine symptoms: reduced power, rough idle, lower MPG
• Cabin symptoms: weak HVAC airflow, musty or stale odors
• Local factors: dust from nearby trails and seasonal pollen
