Upgrade your AMC V8 with the Top Street Performance Black Aluminum Dual Plane Air Gap Intake Manifold. Designed for AMC 304, 360, 390, and 401 V8 engines, this AMC air gap intake manifold is engineered to deliver cooler air charge temperatures, improved airflow efficiency, and stronger throttle response for street performance, street/strip, muscle car restoration, and weekend cruiser applications.

The advanced dual-plane air gap design helps isolate the intake runners from engine heat, reducing heat transfer into the intake manifold and allowing the incoming air/fuel mixture to remain cooler. Cooler intake temperatures can help improve combustion efficiency, increase power potential, and deliver stronger mid-range torque throughout the operating range. This makes it an excellent upgrade for enthusiasts searching for an AMC 360 performance intake, AMC 401 performance intake, AMC 4-barrel intake manifold, or AMC street performance intake manifold.

Designed to perform from 1,500 to 6,500 RPM, this AMC dual plane air gap intake manifold combines excellent low-speed drivability with improved upper-RPM airflow characteristics. The lightweight black aluminum construction helps reduce weight while adding a show-quality appearance to your engine compartment.

Whether you're building an AMC muscle car, upgrading a carbureted AMC V8, completing a restoration project, or assembling a performance street engine, this AMC aluminum intake manifold provides the airflow, cooling benefits, and performance characteristics needed for a responsive and powerful driving experience.

Air Gap Intake Manifold Technology
The Top Street Performance AMC Air Gap Intake Manifold features an advanced dual-plane air gap design that helps separate the intake runners from engine heat. By reducing heat transfer into the manifold, the incoming air/fuel mixture remains cooler, helping improve combustion efficiency and overall engine performance. This design makes it an ideal upgrade for AMC 304, 360, 390, and 401 V8 engines used in street performance and street/strip applications.

Performance Benefits
Designed for a 1,500-6,500 RPM operating range, this AMC dual plane air gap intake manifold delivers strong mid-range torque, improved throttle response, and enhanced airflow efficiency. The air gap configuration helps support cooler intake temperatures while maintaining the drivability expected from a dual-plane design. Whether you're upgrading an AMC 360 performance engine or building an AMC 401 street performance combination, this intake manifold is designed to provide consistent power throughout the RPM range.
