Review HOLLEY EFI Mid rise Intake Gm Ls3/l92 105mm Top fits LS3

The Holley EFI Mid-Rise Intake Manifold part number 300-128 is a high-performance intake solution designed specifically for General Motors LS3/L92 engines with a 105mm throttle body. This intake manifold is part of Holley's EFI product line, which is renowned for delivering reliable and powerful fuel injection systems for various applications.

The mid-rise design of this intake manifold offers several advantages over traditional intake manifolds. The runners are raised in the middle to provide better clearance for aftermarket components, such as tall intake valves and larger throttle bodies. This design also allows for easier access to the engine compartment for installation and maintenance.

The intake manifold is constructed from high-quality aluminum, ensuring durability and resistance to corrosion. It comes with integral fuel rails and match-port bungs for fuel injectors, making installation easier and more efficient. The intake ports are CNC-machined to ensure precise dimensions and smooth flow for optimal engine performance.

The intake manifold's runners are designed with a moderate radius, allowing for excellent flow characteristics and power gain across the entire RPM range. The runners are also optimized for use with Holley's EFI systems, ensuring seamless integration and optimal combustion efficiency.

The Holley EFI Mid-Rise Intake Manifold 300-128 is compatible with a wide range of LS3/L92 engines, making it a versatile choice for performance enthusiasts. It is an excellent upgrade for those looking to maximize power and torque while maintaining reliable fuel delivery and easy installation. With its mid-rise design, quality construction, and optimized flow characteristics, the Holley EFI Mid-Rise Intake Manifold is a must-have for any LS3/L92 engine builder seeking superior performance and durability.

The Holley EFI 300-128 mid-rise intake manifold is a popular choice among GM LS3/L92 engine builders for its ability to support 105mm throttle bodies and Holley's electronic fuel injection systems. Here are some potential pros and cons to consider before making a purchase:
