Efi Throttle Body Intake Elbowsuit Ls 4 Bolt T/b 4150 & 4500

this one-piece cast aluminium throttle body intake elbow is designed to allow the use of a gm ls 4-bolt throttle body that can be mounted to a 4150 or 4500 mounting flange on an aftermarket intake manifold. These elbows are perfect for use in high horsepower race applications where a 4150 / 4500 throttle body cannot flow the correct amount of air required. This will allow you to upgrade to a large single throttle body or allow a drive by wire throttle body to be used. Slotted mounting holes on the base allow the elbow to be mounted forward, sideways, or rearward depending on your application. A total height of 130mm is measured from the flange base to the highest point of the elbow. It features 2 x 1/8" npt ports, 1 x -4 orb port and 1 x -6orb port for various accessories inputs/outputs and a gm ls3 map sensor mounting port. Includes map sensor port cover, gaskets & hardware. Available in either natural cast finish or stealth black.
