Upgrade your high-performance engine’s induction system with a Holley GM LS3/L92 Modular Hi-Ram EFI Intake Manifold! This manifold provides an alternative to fabricated sheet metal and is designed for applications without induction system height limits. The modular base accepts a variety of carbureted and EFI tops, while the 6-1/2” runner length and tapered 4.25 in² to 2.77 in² cross-section works with a wide range of engine configurations.

Features and Benefits:
- Perfect foundation for custom induction builds
- Accepts wide range of carbed and EFI tops
- Works with several engine configurations
- Front mount 105mm LS-style throttle body flange
- EFI fuel rails machined for -8AN O-ring fittings
- Durable cast aluminum construction
- Your choice of a natural or black finish
