Air Flow Research Intake Manifolds from Summit Racing Equipment

Going with the Flow

Air Flow Research (AFR) uses modern manufacturing methods, proprietary flow analysis, and comprehensive dyno testing to develop these intake manifolds that provide superior airflow for improved horsepower output.

Eliminator Intake Manifolds for Small Block Chevy

AFR Eliminator Intake Manifolds are available in two designs. The dual plane configuration is for street engines that operate in the 1,500-7,000 RPM range. Single plane versions are recommended for street/strip and racing engines with 3,000-7,500 RPM powerbands. Those are available as-cast or CNC-port matched to AFR 195cc SBC Eliminator Street Heads.

As-cast heads can be port-matched the runners to your cylinder heads for more power. Other features include additional outlets in the rear of the manifold for custom coolant plumbing, cast-in bosses for optional fuel injectors or nitrous nozzles, and squarebore carburetor mounting pads.

Magnum 18-Degree Intake Manifolds for Big Block Chevy

AFR Magnum 18-Degree Intake Manifolds are available for standard and tall deck engines with an operating range of 4,000-8,500 RPM. They can be run as cast, but there is plenty of material around the port openings for port-matching. The manifolds have a Dominator carburetor mounting pad and bosses for fuel injectors or nitrous nozzles. Pair your manifold with AFR Magnum BBC Cylinder Heads for even more horsepower.

Renegade Intake Manifold for Small Block Ford

Designed for use on serious street/strip and competition engines operating from 3,500-8,000 RPM, the Renegade Intake Manifold fits all 8.2-inch deck height blocks. It has a squarebore carburetor mounting pad plus cast-in bosses for fuel injectors or nitrous nozzles. The Renegade is factory port-matched to AFR’s 185cc Renegade Street Cylinder Heads–just bolt it on and go.

Bullitt Intake Manifolds for Ford 429/460

Designed specifically to fit AFR Bullitt Cylinder Heads, Bullitt Intake Manifolds feature a port design borrowed from AFR’s big block Chevy cylinder heads for improved airflow characteristics. Designed to improve performance from 3,000 to 7,500 RPM, the manifolds are available with a squarebore carb pad for street applications or with a Dominator carb pad for race cars or other high-horsepower vehicles that see light street use. Adding fuel injectors or nitrous nozzles is as easy as drilling and tapping the cast-in port bosses.

Summit Racing carries a large selection of AFR cylinder heads, intake manifolds, and other parts and accessories for small/big Chevy and Ford, GM LS, and Gen III Mopar Hemi.
