NACA Ducts

NACA Ducts

 Low-Profile High-Efficiency Air Intake Solution

Designed for motorsports, automotive fabrication, and custom engineering applications, our NACA ducts provide efficient airflow management while maintaining a clean, low-profile installation.

Originally developed by the National Advisory Committee for Aeronautics (NACA), these ducts use carefully engineered geometry to capture and direct airflow with minimal aerodynamic disruption. Unlike traditional raised scoops or vents, NACA ducts sit flush with the surface, reducing drag while delivering consistent airflow to critical components.

Each duct is designed for applications where space, performance, and appearance matter, including brake cooling, engine bay ventilation, electronics cooling, intercooler ducting, cabin ventilation, and custom vehicle builds.

Features:

• Low-profile aerodynamic design
• Efficient airflow capture with minimal drag
• Ideal for motorsports and performance applications
• Suitable for composite panels, sheet metal, body panels, and custom fabrication
• Great for brake cooling, engine cooling, electronics, and ventilation systems
• Designed for easy integration into custom builds
• 2" width opening is 4.5" long pocket
• 3" width opening has 6.75" long pocket
• 4" width opening is 9" long pocket
  
• Ramp options are 4, 6, 8 and 10 degrees.
