LS3 Low Ram Intake Kit Single Injector Frt Feed

The Holley EFI Ultra Lo-Ram Intake Manifold Kit (Part Number: 300-680BK) is a black intake manifold kit designed for forced induction GM LS Gen III and IV engines, specifically those equipped with LS3/L92 cylinder heads. It features a modular design for custom inlet duct and throttle body placement, and supports peak power at 7000-8000 rpm. The kit includes high volume fuel rails and mounting hardware. The plenum flange has a 105 mm opening, compatible with throttle body part number 112-581 or similar. Its low overall height allows for under-hood fitment in a front configuration, facilitating custom throttle body adapters or inlet ducts. It is available with single or dual injector provisions and burst panel flange options. Fuel rail kits include brackets for long (standard length) and short (Pico, or LS7) fuel injectors.
