Pontiac V8 Dual Plane Aluminum Intake Manifold - Satin

Upgrade your Pontiac V8 with the Top Street Performance Dual Plane Intake Manifold. Designed for carbureted Pontiac 326, 350, 389, 400, and 455 engine applications, this satin aluminum intake manifold delivers improved airflow, stronger throttle response, and increased torque throughout the operating range. Whether you're building a GTO, Firebird, Trans Am, LeMans, Catalina, or street-driven Pontiac performance car, this intake manifold is engineered to provide the drivability and performance enthusiasts expect from a modern induction upgrade.

The dual-plane runner design promotes balanced air and fuel distribution while maintaining excellent street manners. By improving airflow efficiency and mixture distribution, the manifold helps deliver responsive acceleration, strong low-end torque, and dependable mid-range performance. This makes it an excellent choice for street performance vehicles, cruisers, restoration projects, and mild street/strip applications.

With a 1,500 to 6,500 RPM operating range, this intake manifold is optimized for the RPM range most street-driven Pontiac engines operate in. The spread-bore carburetor flange supports common Pontiac carburetor configurations while maintaining compatibility with many popular carbureted performance combinations.

Constructed from lightweight 6061-T6 aluminum, the manifold helps reduce weight compared to factory cast iron intake manifolds while improving heat dissipation. The satin finish provides a show-quality appearance, while the low-profile design helps improve hood clearance in many applications.

Whether you're upgrading a Pontiac 400 street machine, building a 455-powered GTO, restoring a Firebird, or improving airflow on a classic Pontiac V8, the TSP Dual Plane Intake Manifold delivers the performance, drivability, and appearance Pontiac enthusiasts demand.
