Description
Developed with performance in mind, Holley EFI LS single plane split-design race intake manifolds feature a race bred, 2-piece split design that was previously found only on the most expensive race intakes. These manifolds will fit GM LS Gen III engines with cathedral port heads for high performance/racing engine applications with 5.3 to 6.2 liter displacement and maximum engine speeds of 6,000 to 7,000 rpm, depending on the engine combination. The single-plane design provides optimal performance across the rpm spectrum, while the split feature, which allows disassembly of the intake for direct access to internal plenum and port surfaces, makes custom porting and matching a snap. Shoulder bolt locators and an O-ring seal makes reassembly simple and precise.
