Holley LS Modular Lo-Ram EFI intake manifolds are designed for GM LS Gen III and IV engines equipped with GM LS1/LS2/LS6 (cathedral port) 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 applications and a 105 mm throttle or similar models. The base intake manifold is designed with a lower overall height to fit under a stock or mildly modified hood in the front-feed configuration. The modular design allows the use of front-feed plenum entry, while intake design facilitates custom inlet duct and throttle body placement. Additional features and specs: * Cast aluminum construction with satin silver finish * Modular design allows the use of front-feed plenum entry * Clears 4th Gen Camaro and C5 Corvette cowls and hoods without modification * With forced-induction and the short runner length the engine rpm at which peak power occurs is more likely to be coupled to the supercharger or turbocharger being used * High-volume fuel rails and mounting hardware included with 3/4 in.-16 O-ring ports (8 AN) * Fuel rail kits include 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
