Holley 5.0L EFI intake manifolds may be emissions-legal, but don't let that fool you into thinking they're restrictive--they flow tons of unrestricted air! They feature a 2,000 to 6,500 rpm power band, external EGR-passage maximized port and runner sizes, and they retain the stock injector and water outlet locations. The lower manifold ports match up to Holley cylinder heads, so you can be assured of getting the perfect match in the perfect power setup.

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
