EFI High Rise Single Plane Intake Manifold - SATIN - RB Eng

Our high rise single plain RB (413/426/440) intakes are designed for competition applications where the desired powerband is between 3500-7500 RPM. This version is similar to our 146-1029, except it is setup with direct port fuel injection bosses as shown. These feature a standard 4150 carb base, and standard port window (non Max Wedge) intake ports. We recommend using these with CNC ported heads, such as our CNC Steath, Trickflow 240's and similar.
