Wilson Manifolds' lightweight billet elbows provide the most efficient method of adapting their high-flow, single-bore throttle bodies to 4150 or 4500 series intake manifolds. Wilson Manifolds' elbows incorporate a computer-optimized transition from the throttle body to the intake manifold plenum for maximum airflow and distribution. Wilson Manifolds' elbows are CNC-machined to match each throttle body size.

This elbow is designed to mate our 123mm billet throttle body (#471123V) to a 4500 series intake manifold. It utilizes a V-Band provision to mate the throttle body to the elbow. We offer the V-Band completion kit so that you can get the whole package in one place.
