CAC Transition Hose 4in Inlet to 3.5in Out

The CAC Transition Hose 4in Inlet to 3.5in Out from Vibrant Performance is a precision-engineered intercooler connection designed for turbocharged and supercharged engine builds where diameter reduction is necessary downstream of the charge air cooler. This transition hose bridges the gap between larger CAC outlet piping and smaller downstream components, maintaining boost pressure integrity while accommodating varied intake manifold or throttle body configurations.

Manufactured by Vibrant Performance, this transition hose features a design that preserves internal diameter consistency and minimizes boost loss at the inlet-to-outlet step. The 4-inch inlet couples directly to standard CAC discharge ports, while the tapered 3.5-inch outlet accommodates most aftermarket or OEM intake paths without fitment modifications. The construction is designed to withstand high compressor discharge temperatures, ensuring durability and performance.

Ideal for builders working with performance street cars or dedicated track builds, this hose eliminates the need for multiple elbows and reduces turbulence at the transition point. At 0.67 lbs and compact dimensions, installation is straightforward and doesn't add unnecessary weight to your engine bay. This product is perfect for optimizing cooling efficiency and maintaining boost pressure in high-performance applications.
