Chillout Systems Neoprene 4" Air Duct Hose - 6ft

• Coated spring-steel wire support helix prevents hose collapse under pressure and through tight routing paths
• Neoprene-impregnated fiberglass fabric cover and fiberglass cord construction — flexible, pliable, and structurally strong
• Rated from -45°F to 330°F — suitable for cockpit, underhood, and intake ducting applications
• 4" interior diameter, 6-foot length
• Ideal for routing fresh air to a Chillout Systems Quantum Cooler, cockpit ventilation, air intake-to-airbox, and airbox-to-throttle body connections
• Also available in 12-foot length for more complex routing requirements

Routing fresh air efficiently through a race car is harder than it looks — tight bends, high underhood temperatures, and the constant vibration of competition can cause lesser hoses to kink, collapse, or degrade quickly. The Chillout Systems 4" Neoprene Air Duct Hose is engineered to handle all of it without complaint.
The structural backbone of this hose is a coated spring-steel wire support helix embedded throughout the length of the hose, preventing collapse even through tight routing paths or under sustained negative pressure. The outer cover and internal fiberglass cord are both impregnated and coated with neoprene rubber, delivering a construction that is simultaneously flexible, pliable, and structurally robust — qualities that matter when you're threading 6 feet of hose through a congested cockpit or engine bay.
The temperature rating is where this hose truly stands apart: rated from -45°F to 330°F, it handles everything from cold early-morning grid starts to sustained underhood heat without degrading. That range makes it equally at home routing cool fresh air from a Chillout Systems Quantum Cooler to a driver cooling garment, delivering cockpit ventilation, connecting an air intake to an airbox, or linking an airbox to a throttle body.
With a 4" interior diameter and 6-foot length, it covers the most common motorsport ducting requirements straight out of the box. A 12-foot option is also available for more complex routing needs.
