The FIVESTAR Nose Air Inlet Extension is a performance-focused radiator duct designed to optimize airflow management in high-performance racing and off-road applications. This black plastic inlet extension, part number 000-409-NP, functions as a critical cooling system component by directing ambient air to the engine's radiator during operation. Built as part of the Bump n Run radiator duct lineup, this extension addresses cooling inefficiency in competitive environments where sustained engine loads demand maximum thermal management.
Measuring 32 inches in length with a 10 x 6 inch profile and weighing 1.65 lbs, the inlet extension integrates seamlessly with existing radiator systems to enhance airflow dynamics. The plastic construction provides weight savings critical for racing applications while maintaining structural integrity under vibration and thermal cycling. The nose-mounted positioning allows air entering the vehicle's front fascia to be channeled directly to the radiator core, reducing hot-spot buildup that degrades cooling efficiency during sustained acceleration, hill climbs, or prolonged throttle application.
This component is engineered for drag racing, circle track racing, desert racing, and high-performance street applications where engine bay temperatures directly impact reliability and performance consistency. Drivers seeking to lower coolant temperatures without upgrading to larger radiators benefit from the passive airflow improvement this extension provides. Installation requires compatibility verification with your vehicle's cooling system configuration and front-end geometry to ensure proper duct alignment and effective air delivery.
The FIVESTAR brand's Bump n Run radiator duct system represents a cost-effective cooling enhancement alternative to radiator replacement for competitors operating within strict budget parameters or limited modification rules. Verify OEM fitment specifications and vehicle-specific duct routing before purchase to confirm compatibility with your exact model and cooling configuration.
