These snap-on extenders are custom-shaped for the 5th Generation Toyota 4Runner so they attach directly to the factory under-seat vents and deflect the air upward where people actually sit. Made from heat-resistant black PETG, the pair blends discreetly with the interior while standing up to temperature changes inside the vehicle.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these vent extenders improve rear passenger comfort?\u003c\/h3\u003e\n\u003cp\u003eBy changing the direction of airflow from downwards into the floor to upwards into the cabin, these deflectors deliver more conditioned air to second and third-row passengers.
