CAC Transition Hose 3.5in Inlet to 3in Out

The CAC Transition Hose 3.5in Inlet to 3in Out by Vibrant Performance is an essential component for turbo and supercharged engine builds, designed to facilitate stepped diameter transitions in charge air cooler (CAC) plumbing. This hose effectively bridges the gap between mismatched inlet and outlet ports, preventing air leaks and pressure losses that can hinder boost delivery and cooling efficiency.

Constructed from reinforced silicone with internal spring wire support, this transition hose accommodates the 3.5-inch inlet to 3-inch outlet transition while maintaining its structural integrity under boost pressure and thermal cycling. The tapered design minimizes turbulence and pressure drop, ensuring optimal intercooler effectiveness and supporting aggressive tuning targets without complicating the intake system.

This transition hose is particularly beneficial for builders and tuners working with V6 twin-turbo platforms, LS-based forced induction swaps, and custom intercooler configurations. It addresses common fitment challenges without the need for costly custom bends or welded fabrication, making it a versatile solution for high-performance applications.
