Preheat the air fryer to 400°F (200°C).
Place the corn in the air fryer basket and cook for 12-15 minutes, turning halfway through, until tender and lightly charred.
In a small bowl, mix mayonnaise, sour cream, garlic powder, smoked paprika, and chili powder.
Remove the corn and brush generously with the creamy mixture.
Sprinkle cotija cheese and chopped cilantro over the corn.
Serve with lime wedges and a pinch of salt if desired.
