Description

Part #: 300-670

The Holley LS3 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 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-feed configuration. Additional manifold designs include both single and dual injector options. Available with both as-cast satin and black power-coat finishes. High volume fuel rails for eight and sixteen injector configurations. Mounting hardware included with 3/4-16 O-ring ports (8 AN)
