Hyundai Sonata Cabin Air Filter and Engine Air Filter

Each row links to the full specification for that generation, including trim-by-trim breakdowns and the part numbers. Where engines within a generation differ, that page separates them.

The air filters on a Hyundai Sonata is set by its generation, not its model year, so each generation has one page carrying the complete figures, part numbers and fitment notes for every year it covers.

Where is the cabin air filter on a Hyundai Sonata?

How often should the cabin air filter be replaced on a Hyundai Sonata?
