Chillout Systems Neoprene 4" Air Duct Hose - 12ft

• Coated spring-steel wire support helix prevents collapse across the full 12-foot length, even through tight or complex routing paths
• Neoprene-impregnated fiberglass fabric cover and fiberglass cord — flexible, pliable, and structurally strong
• Rated from -45°F to 330°F — suitable for cockpit, underhood, and intake ducting applications
• 4" interior diameter, 12-foot length — ideal for longer runs where the 6-foot version won't reach
• Suitable 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 6-foot length for simpler, shorter installations

Everything that makes the Chillout Systems 4" Neoprene Air Duct Hose the trusted choice for motorsport ducting — now in a 12-foot length for builds that need more flexibility in routing. Whether you're working around a complex roll cage, routing air from a remote inlet to a driver cooling system, or connecting intake components separated by a longer run, the 12-foot version gives you the reach to do it right without splicing or compromising the installation.
The coated spring-steel wire support helix runs the full length of the hose, preventing collapse regardless of how tightly the hose is routed or how much sustained airflow is passing through it. The fiberglass fabric cover and internal fiberglass cord are both neoprene-impregnated and coated, giving the hose its characteristic combination of flexibility, pliability, and structural strength — qualities that become even more important over a longer run where the hose needs to hold its shape through multiple bends and contact points.
A temperature rating of -45°F to 330°F covers the full spectrum of motorsport environments, from routing fresh air to a Chillout Systems Quantum Cooler in the cockpit to underhood applications such as intake-to-airbox or airbox-to-throttle body connections where heat soak is a constant concern.
With a 4" interior diameter and 12 feet of usable length, this hose handles even the most demanding routing challenges in a single, uninterrupted run. Also available in 6-foot length for tighter, simpler installations.
