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

• Engine air filters protect the engine’s combustion process; cabin air filters clean the air inside the passenger compartment for improved comfort and allergen control.
• Both should be inspected regularly; swapping both at recommended intervals prevents reduced performance and protects HVAC and engine systems.
• Repairs covered under warranty must be performed at a certified dealership to maintain coverage—Stevinson Hyundai employs factory-trained technicians and uses OEM parts to protect your investment.

What are signs of a bad air filter?

• Reduced engine performance, poor throttle response, increased fuel use, unusual smells in the cabin, or weak HVAC airflow can indicate clogged filters.
