Advanced Engine Design 60721 Drop Leg Carburetor Booster .140 Orifice (4-Pack)

The Advanced Engine Design 60721 drop leg carburetor boosters are precision-engineered venturi components designed to optimize fuel atomization and throttle response in performance carburetors.

Key Features:

• .140-inch orifice diameter for precise fuel delivery
• Drop leg design positions the booster venturi deeper into the main venturi for improved low-speed signal
• Enhanced fuel atomization compared to straight-leg boosters
• Expertly manufactured from premium materials for durability and consistent performance
• Compatible with Holley and similar performance carburetors

Drop leg boosters work by positioning the booster's own venturi mechanism at the optimal point within the carburetor's venturi bore. This design creates stronger carburetor signal at lower engine speeds, improving throttle response and fuel delivery characteristics. The angled leg design allows the booster to receive vacuum signals more quickly than traditional straight-leg boosters, making them ideal for performance applications where responsive fuel metering is critical throughout the entire RPM range.

Application: Suitable for Pro Street, drag racing, circle track, marine, and off-road performance applications. Requires an AED booster installation tool for proper installation.
