These elbows were developed by the Edelbrock engineering team using the latest in Computational Fluid Dynamic software. Edelbrock Throttle Body Elbows are the best way to adapt LS1, LS2 and Ford 5.0L-based throttle bodies to EFI manifolds with traditional square-bore mounting pads. An internal divider optimises flow quantity and distribution into the manifold and they can be mounted forward, backward, or sideways on Victor EFI square-bore manifolds. Three versions allow EFI tuners to position the throttle body low for hood clearance or higher for maximum airflow. Available in as-cast or black powder coated finish. All Edelbrock Throttle Body Elbows include a universal throttle cable bracket.
