  • Power Band 2500-7000 rpm
  • Height Front 4.23 in. Rear 5.33 in.
  • Port Size 2.05 in. Height 1.02 in. Width
  • Lower Throttle Body Mounting Height To Help With Hood Clearance
  • Fuel Rails With Bracket Allowing Different Height Fuel Injectors
  • Fuel Injectors Are Not Included
  • Fuel Rail Designed For Maximum Throttle Lever Clearance
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 dens ity 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.
