Helmet A/C Cooling Duct for 718 Cayman GT4 Clubsport

Stop losing the race to heat exhaustion. This GT4 A/C air duct from TYP3D replaces the compromised OEM cooling path with a reverse-engineered, CFD-validated design that routes cold air exactly where a driver needs it most. Built, tested, and proven performance in GT4 America.

Features

• Universal Fit with generic 1.25 inch flex duct helmet vent hose, no adapters required.
• 3D printed in high-performance material. Made of ASA, it has excellent heat resistance and UV resistance, perfect for harsh race environments
• Reverse-engineered from LiDAR scans, modeled for exact-fit accuracy
  
• CFD-simulated and track-proven performance. Airflow verified before production. Installed and raced in GT4 America. 
• GT4 regulation compliant. Built to meet class technical requirements out of the box
  

Performance Gains

Helmet cooling is the difference between a sharp driver in the final laps and one who's fading. This helmet cooling duct increases A/C air velocity by 122% over stock, delivering a measurably stronger, more consistent stream of cold air to the driver throughout the race. Less heat fatigue means sharper reactions and a driver who's still racing hard. This isn't just a comfort upgrade, it's a safety upgrade that happens to also help driver focus.

Fitment & Compatibility

• Porsche 718 Cayman GT4 Clubsport (Will not fit GT4/GT4 RS)
• Designed for roll cage equipped chassis with standard A/C ducting routing
• Female coupler accepts standard 1.25 in helmet flex ducting (sold separately)
