The short runner, low-profile base intake manifold intended for forced induction applications was conceived to package with an air to water plenum mounted intercooler with a shorter overall height than possible with other existing intake manifolds. 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 manifolds are designed for forced induction (supercharged or turbocharged) engine applications and the 105 mm throttle body part number 112-581 or similar models. The base intake manifold is designed with a low height to aid the packaging of a plenum-mounted air-to-water intercooler in a top-entry configuration. set for short (such as Pico, or LS7) fuel injectors.
