Carburettor Alloy 3/4" Adapter Square Bore to Spread Bore Manifold

Carburettor Alloy 3/4" Adapter Spacer: Square Bore to Spread Bore Integration

Engineered as a precision die-cast aluminium solution, this Aeroflow adapter spacer bridges square bore and spread bore interfaces with exacting tolerance. The 3/4" thick spacer lets you adapt any square bore carburettor to a spread bore flange on the intake manifold—and it can also be used the other way around to fit a spread bore carburettor to a square bore manifold flange. This flexible design supports robust performance tuning across configurations.

• Precise compatibility to convert square bore carburettors to spread bore intake flanges, and vice versa, for simplified installation and versatile setup.
• Improved air/fuel distribution coupled with reduced fuel temperature for a denser, more stable fuel mixture.
• Vapor lock reduction and added plenum volume help enhance overall engine performance and throttle response.
• Assists linkage clearance on aftermarket or custom throttle cable arrangements, reducing interference during operation.
• Die-cast aluminium construction ensures durability and consistent fitment under performance conditions.

Compatibility & use: Specifically designed to adapt between square bore carburettors and spread bore intake flanges, the spacer accommodates both configurations to simplify installation and tuning for performance applications.
