Review HOLLEY EFI Hi ram Intake Manifold fits RAM LT1

The Holley EFI 090127730515 300-140 Hi-Ram Intake Manifold is a high-performance intake solution designed specifically for LT1 engines. This intake manifold is a part of Holley's EFI line, ensuring seamless integration with Electronic Fuel Injection systems.

This intake manifold is a Hi-Ram design, which means it utilizes high-volume runners to maximize airflow into the engine. The runners taper towards the throttle bodies, creating a swirling effect that enhances the mixture of air and fuel entering the engine cylinders. This design leads to improved combustion efficiency, resulting in increased horsepower and torque.

The intake manifold is constructed from aluminum, which not only keeps the weight down but also provides excellent heat dissipation. This is crucial in high-performance applications where the engine runs hotter than stock. Additionally, the aluminum construction ensures a precise fit and finish.

The Holley EFI 090127730515 300-140 Hi-Ram Intake Manifold is designed to work with LT1 engines using 1.6-inch or 1.7-inch throttle bodies. It comes with all necessary gaskets and hardware for installation, making the process as straightforward as possible.

The intake manifold's design also includes a raised plenum, which helps distribute the air/fuel mixture more evenly to each cylinder. This leads to improved engine performance and consistency, particularly when running multiple carbureted setups or EFI systems.

In summary, the Holley EFI 090127730515 300-140 Hi-Ram Intake Manifold is a high-performance, aluminum intake solution designed specifically for LT1 engines. Its Hi-Ram design, lightweight aluminum construction, and raised plenum contribute to increased horsepower, torque, and improved engine performance. The intake manifold comes with all necessary gaskets and hardware for a straightforward installation.
