Ls Carbureted Intake Dual Plane

Graves Chevy LS Dual Plane Intake Manifold – Grey Aluminum

Give your Chevrolet LS engine the airflow and fuel distribution it needs with the Graves Chevy LS Dual Plane Intake Manifold. Designed for carbureted LS cathedral-port engines, this grey aluminum intake is an excellent choice for demolition derby engines, race builds, LS swaps, and other performance applications.

The dual-plane intake design separates the intake runners and helps distribute the air/fuel mixture more evenly between both banks of the engine. This design can improve low- and mid-range torque, throttle response, fuel distribution, and overall drivability, making it an excellent match for LS engines that need strong, usable power throughout the RPM range.

Constructed from lightweight aluminum and finished in grey, the Graves LS Dual Plane Intake combines performance with a clean, professional appearance.

Engine Fitment

Designed for Chevrolet and GM LS engines using cathedral-port cylinder heads, including many popular:

• 4.8L LS engines – LR4 and other compatible cathedral-port 4.8L applications

• 5.3L LS engines – LM7, L59, LM4, L33 and other cathedral-port 5.3L engines

• 5.7L LS engines – LS1 and LS6

• 6.0L LS engines – LQ4, LQ9 and compatible cathedral-port LS2 applications

• Gen III and compatible cathedral-port LS engine combinations

Does Not Fit

This intake is designed for cathedral-port cylinder heads and is not intended for rectangular-port applications such as:

• LS3

• L92

• L99

• LS7

• LS9

• LSA

• Gen V LT engines

Always verify cylinder-head intake port style before ordering.

Why Use a Dual Plane Intake on an LS?

A dual-plane LS intake manifold divides the intake plenum to help each side of the engine receive a more consistent air/fuel charge. Compared with many single-plane designs, a dual-plane manifold is especially effective when strong low-end torque, mid-range power, throttle response, and consistent fuel distribution are important.

That makes the Graves Dual Plane Intake an excellent choice for demolition derby LS engines, where usable torque and quick throttle response can be more important than making horsepower only at extremely high RPM.
