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

• The engine air filter protects the engine intake and supports combustion efficiency; the cabin air filter cleans incoming air for passengers, reducing dust, pollen, and odors.
• Both are essential: engine filters preserve performance and fuel economy, while cabin filters maintain air quality and HVAC efficiency for a comfortable ride.
• At Arapahoe Hyundai we use OEM-quality filters and clearly explain benefits, warranties, and available discounts — view our service specials or schedule service online.

What are signs of a bad air filter?

• Reduced fuel economy, sluggish acceleration, unusual engine noises, or a dirty HVAC airflow are common signs for the 2012 Hyundai Sonata.
• Bad cabin filters cause musty smells and reduced blower output; engine filters produce drop in performance and sometimes a check engine light.
• Arapahoe Hyundai’s certified technicians will diagnose and recommend the right replacement, and any warranty repairs must be done at a certified dealership to remain valid.

What types of air filters are in a 2012 Hyundai Sonata?

• Your 2012 Hyundai Sonata uses an engine air filter (disposable paper or higher-grade aftermarket options) and a cabin air filter (usually multi-layered paper or activated carbon for odor control).
