This intake will work with OE or aftermarket LS3/L92 cylinder heads. The Ultra Lo-Ram intake manifolds are designed for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm depending on the application. Plenum top has a machine flange for the use of a 6-1/8" x 3-1/8" burst panel (not included). The Ultra Lo-Ram plenum flange has a 105 mm opening to work with Holley throttle body part number 112-581 or similar models. Very low overall height to fit under stock or mildly modified hoods. Even clears the low C6 Corvette hoodline. Modular design allows fabrication of special throttle body adapters or inlet ducts for custom installations.

Rail kit comes with two sets of brackets, a set for long (usually standard length) fuel injectors and a set for short (such as Pico, or LS7) fuel injectors. Designed for single (1 per cylinder) injector applications. For dual injector applications with burst panel provision, use #300-684. Mounting hardware and gaskets are included.;
