The Holley LS3 Ultra Lo-Ram intake manifold kits are designed for GM LS Gen III and IV engines equipped with GM LS3/L92 cylinder heads. These intake manifolds will work with OE or aftermarket cylinder heads.

The base intake manifold is designed with a lower overall height to fit under a stock or mildly modified hood.

Available with single or dual injector provisions and a burst panel flange options.The fuel rail kits come 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.
