3.5 30 Deg Radius Elbow

The 3.5 30 Deg Radius Elbow by BOYCE is a precision-engineered component designed for builders and mechanics who require reliable flow dynamics in custom intake and exhaust manifold applications. This elbow fitting is essential for routing ducting and piping around engine bay constraints, ensuring smooth transitions that prevent turbulence and maintain optimal fluid velocity.

The 3.5-inch nominal diameter accommodates mid-sized ducting applications, making it ideal for various projects, including turbo intake tracts and performance exhaust systems. The 30-degree radius design helps distribute flow stress gradually across the bend, reducing turbulence and minimizing backpressure that can compromise engine efficiency.

This elbow fitting is suitable for both gasoline and diesel engines, making it a versatile choice for fabricators, engine builders, and DIY mechanics. Its quality construction ensures structural integrity under vibration and thermal cycling, critical in high-performance environments where cheaper alternatives may fail.
