Edelbrock 3815 High-Flow 120mm EFI Intake Elbow for 4500 Series Manifolds

The Edelbrock 3815 High-Flow EFI Intake Elbow is engineered for extreme performance applications, designed specifically for naturally aspirated EFI engines and forced induction systems producing over 1,100 horsepower. This precision-machined casting delivers maximum airflow for turbocharged and centrifugal-supercharged powerplants.

Key Features:

• CNC-machined 120mm throttle body opening for maximum airflow capacity
• 4.250-inch square throttle body bolt pattern accommodates large-bore throttle bodies
• 5.375-inch square base flange compatible with 4500-series intake manifolds
• 10-degree downward angle (100-degree total angle) optimizes intake runner alignment
• Internal flow divider prevents air concentration at manifold rear for improved distribution
• Versatile mounting options: forward, backward, or sideways configuration
• 8.86-inch overall height with included universal throttle bracket

This high-flow elbow features an internal divider that eliminates the common problem of airflow concentrating at the back of the manifold, ensuring more even air distribution across all cylinders. The precision CNC machining guarantees consistent quality and optimal flow characteristics. Includes universal throttle bracket for simplified installation. For applications using smaller 90mm throttle bodies, see Edelbrock part number 3814.
