NISSAN 16439-JG30C Air Duct Clamp

The genuine OEM 16439-JG30C NISSAN air duct clamp (CLAMP DUCT) is a precise and secure fastening component designed for internal combustion engine intake systems. The primary function of this clamp is to provide a leak-free, reliable seal for the intake hose, ventilation ducts, and flexible or rigid air lines between the mass airflow sensor and the throttle body. Accurate seating and uniform clamping force prevent unmetered (false) air from entering the intake tract, protecting the engine from fuel mixture issues, rough idling, and the ingress of unfiltered contaminants.
