How often should I change the engine air filter on my 2021 Hyundai Santa Fe?

• Inspect at every oil change; replacement intervals depend on driving conditions but typically occur every 12,000–30,000 miles. Severe dust or towing may shorten that interval.
• Our technicians at Stevinson Hyundai will recommend the ideal interval for your driving habits and record service history to protect resale value and warranty coverage.

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

• The engine air filter protects engine performance and fuel economy by cleaning intake air; the cabin air filter protects passengers from dust, pollen, and odors entering the HVAC system.
• Both filters affect comfort and longevity: a clogged engine filter stresses the engine; a clogged cabin filter reduces HVAC efficiency and interior air quality.
• Stevinson Hyundai uses OEM filters, documents replacements, and honors warranty requirements — warranty repairs must be performed at a certified dealership like ours.

What are signs of a bad air filter?

• Engine filter: reduced acceleration, poor fuel economy, unusual engine sounds, or check-engine alerts.
• Cabin filter: weak HVAC airflow, unpleasant odors, or increased dust on the interior surfaces.
• If you notice symptoms, visit Stevinson Hyundai for a quick inspection — you can schedule service online and see our latest service specials.
