Holley EFI 300-240F EFI Throttle Body Intake Elbow 105mm 4150 Flange Ford

The Holley EFI 300-240F EFI Throttle Body Intake Elbow is a precision-engineered adapter designed to seamlessly connect a Ford throttle body to a traditional 4150-style intake manifold flange. With a 105mm throttle body opening and a 100° mounting angle, this elbow provides optimized airflow geometry for high-performance EFI applications.

Constructed from sand-cast aluminum with a satin finish, this intake elbow delivers both durability and a clean, professional appearance. The design includes slotted mounting holes that allow forward, sideways, or rearward throttle body positioning, giving builders the flexibility needed to clear hood lines, brake boosters, and other engine bay obstructions.

Key Features:

• Overall height: 5.12"
• Sand cast aluminum construction with satin finish
• Compatible with Ford throttle bodies
• Fits intake manifolds with a 4150 carburetor flange
• 105mm throttle body opening at a 100° mounting angle
• LS3-style MAP sensor mounting boss for convenient sensor integration
• (2) throttle linkage mounting bosses for versatile cable or rod linkage setups
