Description

Holley LS1/2/6 Ultra Lo-Ram intake manifold kits are for GM LS Gen III and IV engines with LS1/2/6 (cathedral port) cylinder heads (OE or aftermarket). Designed for forced induction (supercharged or turbocharged) applications, it works with a 105 mm throttle body (P/N 112-581 or similar). The low-profile design fits under stock or mildly modified hoods. The 300-621 Lo-Ram plenum entry provides a very low profile modular intake manifold suitable for turbocharged or centrifugally supercharged engines. Fuel rail kits include brackets for both long (standard length) and short (Pico, LS7) fuel injectors.
