The new single plane EFI (Electronic Fuel Injection) intake manifold is designed to provide a broad RPM powerband for high-performance street/strip engine applications to a maximum engine speed of 7500 RPM. The manifold is designed to work with 4150 Style Throttle body EFI systems like the Holley 4150 style 112-587 and 112-588. These intake manifolds are designed to accept most stock hardware and accessory brackets, but offer performance features; like an updated plenum divider area, a 1 shorter overall height than most single plane manifolds, and a choice of two distributor clamp locations. The isolated design of the air/fuel passages helps to increase charge air density and performance. The fuel injector bores have back-cut exits in the runners for better fuel atomization.

This design points the injectors at an angle to match the intake runner airflow angle. The black coated fuel rails and rail bracket assortment are included with the manifold for any easy installation with the injectors that you choose to use for your combination. Fuel rail designed for maximum throttle lever clearance.

Single plane design with isolated plenum to keep the air charge cooler. 4150 square bore mounting flange to adapt most aftermarket throttle body designs.

Height: Front 4.23", Rear 5.33". Port Size: 2.05 height 1.02 width. Lower throttle body mounting height to help with hood clearance.

Black coated fuel rails with bracket assortment allowing different height fuel injectors. Fuel injectors are not included. Please contact before ordering if you are not 100% sure of fitment.
