This heater floor air duct hose is designed for 1974–1995 Jeep CJ5, CJ6, CJ7, CJ8, and Wrangler YJ models, providing a direct replacement for OE part number 55035618 and aftermarket reference 17907.05. It restores proper airflow from the heater system to the floor vents. The duct hose channels warm air from the heater box to the lower cabin area, helping maintain interior comfort in cold conditions. Over time, original ducts can crack, break, or become disconnected, resulting in reduced airflow and uneven heating. Engineered for a precise fit, this hose installs in the factory routing and connects directly to existing heater components for straightforward replacement. Constructed from durable materials, this component is designed to withstand heat and repeated use while maintaining flexibility and proper airflow. Ideal for replacing damaged or missing ducts, this component helps restore effective cabin heating and improve overall comfort.
