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.
