Vibrant 11867 CAC Transition Hose Coupler to ID - 4.00 3.50

The Vibrant Performance 11867 is a charge air cooler (CAC) transition hose coupler designed to connect intercooler piping of different diameters in forced induction applications. This reducer coupler features a 4.00-inch inner diameter on one end transitioning down to a 3.50-inch inner diameter on the other end, allowing seamless integration between mismatched pipe sizes in turbo and supercharger systems.

Key Features:

• Precision-engineered silicone construction for superior heat and pressure resistance
• 4.00-inch to 3.50-inch inner diameter transition design
• Multiple reinforcement layers for durability under boost pressure
• Smooth internal surface promotes optimal airflow with minimal turbulence
• Compatible with standard T-bolt or worm gear clamps
• Temperature resistant from -40°F to 350°F for extreme performance applications

Ideal for custom intercooler piping installations, turbo upgrades, and charge air cooler systems where connecting different diameter pipes is required. Vibrant Performance couplers are engineered to withstand the demanding conditions of high-performance forced induction systems while maintaining flexibility for easy installation.
