2" Tapered High Velocity Carburettor Spacer Raw Finish Suit 4150 Style Flange

2" Tapered High Velocity Carburettor Spacer for 4150 Style Flange

Engineered by Aeroflow to optimize intake performance, this 2" tapered high velocity carb spacer accelerates the fuel/air charge as it enters the carburettor. Crafted from 6061-T6 billet aluminium, it delivers precise fitment and lasting durability while minimizing heat transfer to the carburettor for more consistent performance under demanding conditions.

The tapered geometry creates a high-velocity plume that enhances fuel atomization and throttle response, particularly during rapid acceleration. By insulating the carburettor from the manifold, it reduces heat soak and helps maintain stable air/fuel temperatures, supporting reliable power delivery across the RPM range.

Designed to suit 4150 Style Flange carburettors, this spacer offers reliable sealing and straightforward installation. Choose between a raw finish or a black anodized finish to match your engine bay aesthetics and add protection against the elements.
