45 Degree Transition Hose 3in I.D. to 3.5in

The 45 Degree Transition Hose 3in I.D. to 3.5in by Vibrant Performance is designed for builders and mechanics who require precision in custom intake and cooling system plumbing. This transition hose addresses the need for a smooth diameter step-up in modular engine builds, particularly where turbocharger outlets, intercooler piping, or radiator hose routing are involved.

Manufactured by Vibrant Performance, a reputable name in high-flow intake and exhaust systems, this hose features reinforced construction to withstand boost pressure, coolant flow, and thermal cycling. The 45-degree geometry allows for flexible routing in tight engine bays while maintaining laminar flow, which is essential for intercooler efficiency and cooling system pressure stability. The gradual transition from a 3-inch inner diameter to a 3.5-inch outlet minimizes flow separation and reduces pressure loss.

This transition hose is particularly beneficial for serious street and track builders, as it eliminates the need for multiple adapters and bunched connections that can compromise both aesthetics and system efficiency. It is compatible with standard automotive hose clamps and integrates seamlessly into custom hard-line or soft-line systems using barbed or flange adapters.
