Official Release:

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, mounting hardware and 4150 mounting pattern allowing racers to use a variety of throttle body and intake elbow combinations.

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.

Features:

• Maximum performance race design with hood clearance consideration.
• Lighter than other split race intakes.
• Billet fuel rails and rail mounting hardware included.
