It comes with a handheld controller and windshield mount, an LS-compatible ECU, injectors, a fuel rail set, and the required installation hardware. The plug-and-play configuration and compatibility with both 24x and 58x crank and cam signals make it a straightforward upgrade for modern LS applications.

      Application. This FiTech Fuel Injection Ultimate LS1/LS2/LS6 750HP Intake Manifold Kit has a universal fit.
