Chrysler Mopar 426 440 HiRise Intake Manifold EFI Version [Machine Polished]

Speedmaster EFI intake manifolds make it simple to convert competition engines to electronic fuel injection. They have injector bosses precisely positioned and machined for excellent fuel spray patterns and maximum power. These manifolds require a universal 4-barrel throttle body, fuel rail set, fuel injectors, fuel pump, and regulator, which are each sold separately.
