45 Degree Transition Hose 3in I.D. to 2.75in

The 45 Degree Transition Hose 3in I.D. to 2.75in from Vibrant Performance is engineered for custom intake and cooling system modifications where diameter reduction is critical. This molded adapter hose addresses a common challenge in engine bay plumbing: smoothly transitioning between 3-inch and 2.75-inch diameter components without turbulence or flow restriction. Whether you're building a turbo intake manifold, upgrading intercooler piping, or optimizing radiator hose routing, this transition fitting eliminates the need for crushed or kinked hoses that compromise performance and longevity.

Constructed with reinforced silicone and precision molding, the 45-degree angle reduces pressure drop and turbulence compared to stepped fittings or aluminum adapters. The gradual taper allows coolant, boost, or intake charge air to transition smoothly between bore sizes, maintaining consistent flow velocity and minimizing heat loss. Vibrant Performance's manufacturing tolerances ensure a reliable seal at both ends, while the flexible silicone construction accommodates typical engine vibration without cracking or separating. At 0.9 pounds and compact overall dimensions, this hose integrates easily into space-constrained engine compartments without requiring extensive rerouting of adjacent components.

Mechanics and enthusiasts building forced-induction systems, custom cooling loops, or high-flow intake manifolds rely on transition hoses like this to maintain system integrity under boost pressure and elevated temperatures. Installation is straightforward: slip the 3-inch I.D. end onto your larger diameter tube, secure the 2.75-inch outlet to your smaller component, and tighten hose clamps at both ends for a permanent seal. This hose performs reliably in both street and racing applications where clean, efficient ducting directly impacts engine efficiency and cooling response. For any custom automotive project requiring a 3-inch to 2.75-inch step-down, this Vibrant Performance transition hose delivers proven durability and optimized flow.
