The Holley LS1/2/6 Lo-Ram intake manifold kits are designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads. These intake manifolds will work with OE or aftermarket cylinder heads. The Lo-Ram intake manifold has been designed for forced induction (supercharged or turbocharged) engines where the short runner length and higher engine RPM applications are an ideal fit. The intake is designed to work with the Holley EFI 105mm throttle body Part # 112-581 (sold separately). 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 300-621 Lo-Ram front-feed plenum entry was configured to provide a very low profile modular intake manifold suitable for turbocharged or centrifugally supercharged engines.
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.
