This intake manifold is part of the Holley Sniper EFI system, which is known for its exceptional power potential and ease of installation.

This intake manifold is a dual plenum design, which means it utilizes two separate runners to feed each cylinder bank.

It is also CNC machined for precise dimensions and fitment. The manifold includes a built-in fuel pressure regulator, which simplifies installation and eliminates the need for an external regulator.

The intake runners are designed with a large velocity stack entrance to reduce turbulence and improve airflow to the throttle bodies. The runners also include a rectangular port design, which is more efficient in delivering fuel to the engine compared to round ports.

The Holley Sniper EFI 820242 Intake Manifold includes a gasket kit and all necessary hardware for installation. It is also compatible with Holley's EFI accessories, such as fuel pressure sensors, temperature sensors, and idle control valves, making it a complete intake solution for your LS engine.

In summary, the Holley Sniper EFI 820242 Intake Manifold is a high-performance, dual plenum intake solution for LS1, LS2, and LS6 engines using 102mm throttle bodies and 6 or 10 injector rails. It features a large volume design, built-in fuel pressure regulator, and precise CNC machining for optimal fitment and power potential. With its sleek finish and ease of installation, this intake manifold is an excellent choice for anyone looking to upgrade their LS engine with a high-performance EFI system.
