The New-Line & EM Tech F-DUCT is a purpose-built airflow management solution designed to improve radiator efficiency by directing clean, high-velocity airflow straight through the radiator core.
Rather than increasing radiator size, the F-DUCT improves how air is delivered to the radiator, helping stabilize engine temperatures—especially in high-speed or turbulent airflow conditions. This makes it an effective upgrade for karts running near the edge of their cooling window.
Designed specifically to integrate with New-Line and EM Tech radiators, the F-DUCT bolts directly to the underside of the radiator with no modification required.
Key Features:
-
Improves radiator cooling efficiency through directed airflow
-
Helps stabilize engine temperatures without larger radiators
-
Reduces airflow turbulence in front of the radiator
-
Lightweight, race-proven design
-
Designed for consistent performance in high-speed conditions
Fitment & Installation:
-
Radiator Compatibility:
Designed for New-Line and EM Tech radiators (all standard core sizes) -
Chassis Fitment:
Fits most full-size racing karts -
Mounting:
Bolts directly to the underside of the radiator using included hardware
No drilling or modification required
Ideal Applications:
-
Shifter karts
-
TAG applications
-
KZ classes
-
Situations where cooling is marginal but radiator size cannot be increased
Notes:
-
Cooling gains depend on airflow, speed, and radiator selection
-
Intended as an airflow efficiency aid, not a replacement for proper radiator sizing
-
Best results achieved when paired with EM Tech or New-Line radiators
