Show original supplier description
The Chevrolet intake manifold, part number 12556333, is a genuine OEM GM component designed for LS1 5.7L engines. This specific unit was acquired from a 30,000-mile vehicle that underwent performance modifications, making the original factory parts available. Key specifications include a plenum volume of 5.06L, runner length of 262 mm, and runner volume of 0.536L. This intake manifold is listed as compatible with 1997-2000 C5 Corvette models featuring the LS1 engine. It is also noted that this manifold can fit any cathedral port head and is suitable for use on LS1, LS2, and LS6 motors. While this is an OEM part, it's important to compare the pictured unit to your existing manifold to ensure it is the correct replacement. The source indicates that this manifold may be a downgrade from LS6 and LS2 intakes, suggesting it is an LS1-specific design. It is not an aftermarket replacement and is sold as-is.
