The Chillout Systems Carbon 4" 90-Degree Air Intake Plenum is the most efficient way to boost airflow and maximize performance from your Quantum Cooler in extreme heat environments. Designed for race cars that demand ultimate ducting efficiency, this 4-inch carbon fiber plenum allows up to 55% more airflow compared to 3-inch ducting, delivering significantly increased cooling potential.

By routing cooler outside air directly into the intake side of the Quantum Cooler, the plenum improves thermal efficiency while also helping reduce electrical amp draw. When the cooling system receives higher-volume, lower-temperature intake air, it operates more efficiently—an important advantage in endurance racing and high-temperature track conditions.

The 90-degree angle allows for compact installation in tight packaging areas and can be mounted facing either direction for flexible duct routing. Weighing just 5 ounces, the lightweight carbon fiber construction adds minimal mass while maintaining durability in high-vibration race environments.

For best performance, a minimum 200 CFM blower is required when used with this plenum.

Whether you're preparing for endurance racing, desert heat track days, or closed-cockpit race cars with extreme ambient temps, the 4" Carbon 90° Air Intake Plenum delivers maximum airflow and measurable cooling gains.
