AFR Eliminator Series intake manifolds are the perfect way to "eliminate" your competition! These cast aluminum performance intakes have a 23-degree manifold configuration. They're designed for standard location intake port cylinder heads. Additional coolant outlets have been added at the rear of the manifold for custom cooling systems. Eliminator intakes can be run "as cast," right out of the box; however, AFR does recommend having the runner exits be "port matched" to your particular cylinder heads for optimal performance. Additional bungs have been cast into the top of the intake runners for EFI injectors or nitrous nozzles. Multiple heights and rpm ranges are available; order the manifold recommended for your application.
