Wilson Manifolds’ new billet elbow offers the most effective way to connect their performance, single-bore throttle bodies to 4500 series intake manifolds. This elbow from Wilson Manifolds features a computer-enhanced transition from the throttle body to the intake manifold plenum, optimizing airflow and distribution. Each elbow is precisely CNC-machined to fit respective throttle body sizes.
