2-3/4in ID x 3-1/2in Lon g Silicone 90 deg Elbow

The 2-3/4in ID x 3-1/2in Long Silicone 90 Degree Elbow is an essential turbo plumbing component designed for high-performance cooling system modifications, intercooler piping, and custom intake manifold fabrication. Built by Vibrant Performance, a trusted name among serious engine builders and tuning shops, this elbow connector addresses a critical need in boost-dependent powerplants: reliable, flexible connections that withstand thermal cycling and vibration without leaking or cracking. Whether you're routing intercooler discharge lines, constructing custom charge-air cooling paths, or rebuilding a turbo intake system, this 90-degree silicone elbow provides the bend geometry you need without welding, adapting, or compromising flow integrity.

Constructed from premium reinforced silicone, the elbow features a 2-3/4-inch inner diameter that matches common turbo discharge and intercooler outlet sizes, while the 3-1/2-inch length provides optimal flexibility and vibration isolation. The 90-degree angle eliminates sharp crimps and maintains smooth bore radius to minimize turbulence and pressure drop across the connection point—critical when managing boost pressure and intercooler efficiency. Silicone's superior temperature range (typically -40°F to 350°F+) ensures this elbow resists thermal degradation far better than rubber alternatives, while reinforced construction handles sustained boost levels without bulging or collapsing under load. The material's natural elasticity absorbs engine bay vibration, reducing fatigue stress on adjacent hard piping and fittings, extending system life and reliability.

This connector is ideal for turbocharged and supercharged platforms, especially LS swaps, Mustang EcoBoost builds, and import performance projects requiring custom intake and cooling modifications. Mechanics and tuners favor Vibrant Performance elbows for their durability during dyno testing and street duty, where temperature and pressure cycling are constant stressors. Installation is straightforward with quality hose clamps (sold separately) at both ends; ensure mating surfaces are clean and use clamp placement 1/4 inch inboard from each elbow end for secure hold. Compatibility spans virtually any silicone hose size ecosystem, making this 2-3/4in 90-degree piece a reliable stock component for serious boost system upgrades.
