AFR Eliminator Intake Manifold, Small-Block Chevy, Dual-Plane, 4150, Up to 6500 RPM

Dual-plane aluminum intake for 302–406ci small-block Chevy engines with a 4150 carburetor flange.

Designed to deliver strong street and strip performance, the Air Flow Research Eliminator dual-plane intake manifold combines optimized airflow with the responsive characteristics of a dual-plane design. Engineered for small-block Chevrolet engines ranging from 302 to 406 cubic inches, this aluminum manifold features intake runners developed around AFR's popular 195cc cylinder head program to provide excellent port alignment and efficient airflow. Its dual-plane configuration promotes strong low- and mid-range torque while maintaining performance at engine speeds up to 6,500 RPM, making it an excellent choice for performance-oriented street engines and weekend racing applications. Cast and machined in the USA, the Eliminator intake manifold features a natural aluminum finish and a square-bore 4150-style carburetor flange. The carburetor mounting pad measures 4.725" in average height, with a 4.200" front height and 5.250" rear height. Additional features include cast-in nitrous bosses for custom nitrous system installations, dual distributor clamp hold-down provisions and front and rear coolant outlets for added cooling system flexibility. Designed for compatible traditional small-block Chevy cylinder head configurations, this manifold is not compatible with TBI/TPI 72° intake bolt patterns and will not clear a stock Corvette hood.
