Billet Elbow 90-105mm - 4500 Flange

The Billet Elbow 90-105mm - 4500 Flange is a precision-engineered intake manifold component designed for high-performance engine builders and serious automotive enthusiasts tackling complex turbo and supercharger installations. This aluminum billet elbow serves as a critical transition fitting between intake pipes and manifold systems, allowing you to custom-route charge air or intake passages while maintaining optimal flow characteristics. Whether you're building a custom engine bay layout, upgrading to larger turbocharged displacement, or adapting non-standard intake geometry, this 90-degree elbow bridges the gap between standard sizing constraints and your unique application requirements.

Manufactured from solid billet aluminum, this elbow features 90-105mm diameter compatibility with a 4500 series flange pattern, ensuring rigid, leak-free connections under boost pressure and high-temperature conditions. The billet construction eliminates the casting porosity common in cast elbows, delivering superior durability and reliability in forced induction environments where thermal cycling and vibration stress weak points. The generous 4500 flange allows for secure bolted attachment to compatible manifolds, intercoolers, or custom intake tubes, while the smooth internal geometry minimizes turbulence and pressure drop—critical factors for maximizing volumetric efficiency and maintaining consistent air-fuel ratios across your power band.

This elbow is ideal for fabricators, engine shops, and DIY builders working on single-turbo conversions, LS swaps, or bespoke forced-induction systems where off-the-shelf piping doesn't fit your bay layout or performance goals. Weighing just 3.26 lbs, its compact footprint (8.4 x 8.3 x 8.5 inches) makes it easy to position in tight engine compartments while maintaining the structural integrity needed under sustained boost. Verify that your flange pattern and intake/manifold diameters match the 90-105mm and 4500 series specifications before ordering; this component is engineered for custom builds and requires compatible adapters or mating surfaces for proper installation.
