45 Degree Elbow 5in I.D. x 4in Leg Length

The 45 Degree Elbow 5in I.D. x 4in Leg Length from Vibrant Performance is a precision intake piping component engineered for custom intake manifold and turbocharger plumbing applications. Whether you're building a high-performance engine bay from the ground up or optimizing airflow through existing intake systems, this mandrel-bent elbow allows smooth directional transitions that minimize turbulence and pressure drop. It's an essential fitting for builders, tuners, and enthusiasts who demand clean, efficient air delivery into their engine's combustion chambers.

Constructed from durable mandrel-bent tubing, this 45-degree elbow features a 5-inch inside diameter inlet paired with 4-inch leg length construction, providing flexibility in routing while maintaining structural integrity under boost and vibration. The mandrel-bending process preserves consistent wall thickness throughout the bend radius, preventing kinking and collapse that would otherwise choke airflow and create unwanted turbulence. Vibrant Performance's design ensures low-restriction transitions ideal for both naturally aspirated and forced-induction applications, making it compatible with intercooler piping, turbo inlet plumbing, and custom intake silencer configurations. Its compact overall dimensions (13.4 x 5.65 x 16.75 inches) and modest 1.37-pound weight make it suitable for tight engine bay layouts without sacrificing rigidity.

Professional builders and weekend fabricators alike rely on this elbow to create seamless intake pathways in custom turbo kits, supercharger installations, and high-flow intake manifold upgrades. The 45-degree angle accommodates directional changes common in modern engine bay configurations while the 5-inch bore maintains velocity for optimal scavenging and volumetric efficiency. Installation requires standard hose clamps or flanged coupling methods; verify your tubing diameters and clearance requirements before ordering. This component pairs effectively with other Vibrant Performance mandrel-bent elbows and straight sections to build complete custom plumbing systems.
