Intake Manifold-EFI SBC 4150 Single Plane Fuel Injection| SPELAB
The new single plane intake manifolds are designed to provide a broad RPM powerband for high-performance street/strip engine applications to a maximum engine speed of 7500 RPM. The EFI manifold is designed to work with 4150 Style Throttle body EFI systems like the SPELAB 4150 style flange Universal Throttle Bodies. These intake manifolds are designed to accept most stock hardware and accessory brackets, but offer performance features like better plenum and runner geometry for improved charge airflow. The isolated design of the air/fuel passages helps to increase charge air density and performance.
Features:
- Single plane design with isolated plenum for cooler charge air temperatures
- 4150 square bore mounting flange
- Power band: 2500-7500 RPM
- Height: front 5.58”, rear 6.40”
- Port size: 1.82” height, 1.04” width
- Extra material allows for porting to 2.00” height, 1.20” width
- Anodized aluminum fuel rails with laser-etched logo (EFI model) 6AN
- Includes fuel rail mounting brackets in two sizes for more options in fuel injectors (EFI Model)
- Accessory ports under the carburetor in 1/8 NPT, 1/4 NPT and 3/8 NPT sizes
- Kit does not work with factory fuel rails and requires the use of SPELAB Fuel Rail Kit -SPIS08520
