The Edelbrock High-Flow EFI Intake Elbow #3815 is intended for very high-power naturally aspirated EFI applications and turbocharged or centrifugal-supercharged engines making over 1,100 horsepower. This casting is CNC-machined to a 120mm opening and has a 4.250-inch-square throttle body bolt pattern with a base flange bolt pattern of 5.375-inch-square for use with 4500-series intake manifolds. The elbow has a 10-degree downward angle for a total of 100 degrees and can be mounted in a forward, backward or sideways configuration. An internal divider prevents flow from concentrating at the back of the manifold, which is a condition that commonly occurs with other elbows. Overall height of the High-Flow Elbow #3815 is 8.86 inches and it comes with a universal throttle bracket. For smaller 90mm throttle bodies, order High-Flow Elbow #3814.
