Holley EFI Throttle Body Intake Elbows make it simple to adapt a single-bore throttle body to 4-barrel style intake manifolds. Fully compatible with both LS and Ford 5.0L throttle bodies, they feature four vacuum ports and slotted mounting holes that let you mount them forward, sideways, or rearward. These CNC-machined elbows have a 105mm throttle opening and a 100-degree mounting angle that creates extra hood clearance. Port-matched to a 4150 gasket to fit any intake manifold with a 4150 flange, they make it easy to bolt on a blower or turbo and feature two throttle-linkage mounting bosses and an LS3-style MAP sensor mounting port. (A billet cover is supplied for those who will not be utilizing a MAP sensor.)
