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 a precision engineered intake manifold component designed for performance vehicles and custom automotive builds. This transition hose bridges two different diameter ducting systems, allowing seamless airflow pathways in turbo, supercharger, or custom intake configurations. Built for professionals and enthusiasts who demand reliable air routing without turbulence or restriction, this component is essential for maximizing engine efficiency and maintaining consistent fuel maps in high-performance applications.

This 45-degree angle design reduces flow separation and minimizes pressure loss across the transition zone, critical factors in maintaining boost integrity and preventing vacuum leaks. The 3-inch inner diameter (I.D.) to 3.5-inch outer diameter step is engineered to accommodate standard hose clamp sizing and create a tight, durable seal under high-temperature and high-pressure conditions. Vibrant Performance's reinforced construction withstands thermal cycling and vibration from engine operation, ensuring longevity in demanding motorsport and street performance environments where standard hoses fail prematurely.

Technicians and engine builders rely on this transition hose for custom intake manifold projects, turbo upgrades, and precision air-routing systems where off-the-shelf intake pipes do not fit. The angled design allows compact routing in tight engine bays while maintaining optimal flow geometry. Installation requires standard hose clamps sized for 3-inch ducting on the inlet side, and compatibility extends to any air system using SAE-standard hose connections. This component is ideal for race vehicles, supercharged platforms, and modified street engines where intake flow optimization directly impacts horsepower delivery and throttle response.
