When you increase the boost on your Cummins, the factory charge air cooler (CAC) boots become a major weak point. They can balloon, tear, or blow off under load, resulting in a significant loss of power and potential engine damage. The Fleece Performance boot is designed to maintain its shape and seal under the most demanding conditions, ensuring that every pound of boost reaches the intake manifold. Its precise 45-degree bend allows for a perfect fit in the factory or aftermarket intercooler piping layout, making installation straightforward and effective. Don't let a failed boot ruin your track day or towing trip. Upgrade your charge air system with the reliability of Fleece Performance at GGCRACING.
