Holley has expanded their line-up of race oriented split-design intake manifolds by releasing two new LS3/L92 versions! A carbureted 4150 flange version gives consumers the ability to go old school and provide an option for a high-winding performance intake that doesn't break the bank! Meanwhile the EFI version also includes fuel rails and mounting hardware allowing racers to use a variety of throttle body and intake elbow combinations. Read on to learn more!

The new Holley Single-Plane Race intake manifold were designed with performance in mind. They feature a race bred, two piece split feature that was previously only found on the most expensive race intakes. The manifold will fit GM LS Gen III engines with LS3/L92 heads and are intended for 4150 style square bore flanged carburetors or throttle body EFI.
  • Captured O-ring seals at head ports and the split.
  • Vacuum port options include (2) 1/8, (1) 1/4, and (1) 3/8, NPT ports at the carb flange.
  • Billet fuel rails and rail mounting hardware included.
  • 33 to 50% the price of other split race intakes!

    • The LS Race single-plane intake manifold was designed for racing engine applications, 5.3 to 6.2+ liter displacement and high-winding performance! This single-plane design provides optimal performance across the RPM spectrum while providing maximum engine speeds up to 7000 rpm, depending on the engine combination.
  • Maximum performance race design with hood clearance consideration.
  • Lighter than other split race intakes.
    • The Holley LS Race manifold incorporates a split feature, which allows disassembly of the intake for direct access to internal plenum and port surfaces, making custom porting and matching a snap. With shoulder bolt locators and O-ring seal, reassembly is simple and precise!
