Overview
Holley EFI LT1 Gen V Lo-Ram Intake Manifolds
Holley is the new standard in EFI! The Holley EFI LT1 Gen V Lo-Ram intake manifolds are designed for GM Gen V LT engines equipped with GM LT cylinder heads. These intake manifolds will work with OE or aftermarket cylinder heads. The Lo-Ram intake manifolds are designed for forced induction (supercharged or turbocharged) engine application. The top-feed plenum base intake manifold is designed with a reduced overall height to fit under a stock or mildly modified hood. The Lo-Ram provides a low-profile modular intake manifold that's suitable for use with plenum mounted air-to-water intercoolers for boosted applications. Various Hi-Ram plenum top options are available to complement the top-feed base intake manifold kits and fabrication flanges are offered to aid fabrication of plenum tops for custom installations.
