How often should I change the engine air filter on my 2012 Ford Flex?

• Generally inspect at every oil change and replace as needed — typical intervals are 12,000–30,000 miles depending on driving conditions; dusty roads require more frequent changes.

• We document service to maintain resale value and can apply available discounts via service specials. Ask about service financing to manage larger maintenance items.

What is the difference between an engine air filter and a cabin air filter?

• The engine air filter protects the powertrain by filtering intake air into the engine; the cabin air filter protects occupants by cleaning air entering the HVAC system.
• Both filters have distinct functions; replacing only one can leave the other compromised — we inspect both during routine service to ensure full protection for your 2012 Ford Flex.
• Our transparent service estimates and use of OEM parts ensure long-term value; warranty repairs must be performed at a certified dealership to remain valid.

What are signs of a bad air filter?

• Reduced acceleration, poor fuel economy, unusual engine noises, or a strong fuel smell can indicate a clogged engine air filter on the 2012 Ford Flex.
• For cabin filters, persistent odors, reduced HVAC airflow, and increased dust inside the cabin are common symptoms.
