2016-24 Camaro/2014-19 Corvette Holley Hi-Ram Intake Manifold – GM LT1
The Holley Hi-Ram Intake Manifold is a high-performance upgrade designed for GM LT1 engines, specifically fitting the 2016-2024 Chevrolet Camaro SS and 2014-2019 Chevrolet Corvette models.
This manifold enhances engine performance by improving airflow and increasing power output, making it an excellent choice for enthusiasts seeking to elevate their vehicle’s capabilities.
Key Features:
• Modular Design: The manifold’s modular construction allows for easy disassembly, facilitating custom porting and the use of various top configurations to suit different performance needs.
• Optimized Runners: Each runner features a large radius at the plenum entry, with optimized taper and cross-sectional area, promoting efficient airflow and enhancing engine performance across a wide range of configurations.
• Multiple Top Options: The manifold offers versatility with several top options, including provisions for single 95mm or 105mm throttle bodies, dual 4150 or 4500 configurations, or a blank flange for custom setups.
• Enhanced Plenum Volume: With a large plenum volume of 549 cubic inches (with a single 95mm or 105mm throttle body top), the manifold supports increased airflow, contributing to higher engine output.
• Fuel Injector Provisions: Models equipped with injector ports include fuel rails designed for dual mounting, accommodating various injector lengths (1.48” or 2.56” O-ring to O-ring). The fuel rails are anodized, laser-etched, and machined for 8AN O-ring fittings at each end.
• Compatibility: Designed for GM Gen V LT1 engines, the manifold is compatible with both original equipment and aftermarket cylinder heads. It supports engine displacements ranging from 427 to 440 cubic inches and is suitable for maximum engine speeds between 7500-8500 RPM.
Installation Considerations:
Due to the manifold’s design, hood modifications may be necessary for proper fitment in most vehicles. Professional installation is highly recommended to ensure optimal performance and to address any custom fitting requirements.
By upgrading to the Holley Hi-Ram Intake Manifold, you can significantly enhance your Camaro SS or Corvette’s engine performance, achieving improved throttle response and increased horsepower.
