The Edelbrock 3849 Intake elbows was developed by the Edelbrock engineering team using the latest in Computational Fluid Dynamic (CFD) 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 optimizes 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 satin or black powder coated finish. All Edelbrock Throttle Body Elbows include a universal throttle cable bracket. High Flow Intake Elbow 3849 can be used with up to a 95mm Throttle Body.
