Chillout 4" Carbon Fiber NACA Duct

Click for a larger picture of Chillout 4" Carbon Fiber NACA Duct

Brand: Chillout Systems

This NACA duct was designed and wind tunnel tested for maximum air flow with minimal drag. It is constructed of tough, lightweight genuine carbon fiber. This is not cheap plastic with a carbon pattern printed on! An integral mounting flange (approximately 9/16" wide) makes them easy to rivet to body panels or bond to composite panels with epoxy.

This large size has an outlet nipple that accepts our 4" duct hose (sold separately). The larger size allows 50% greater airflow than the more common 3" duct. Measures approximately 225mm (8.9") Long x 150mm (5.9") wide including the mounting flange. The maximum depth is approximately 120mm (4.7") from the front face to the outlet nipple. Sold individually.

Note: These ducts are designed and built for racing use. They are not built for show cars. You can sand and paint them, but do not expect a "show-quality" finish out of the box.
