Proflow Carburettor Spacer Aluminium 2in. Thick, 4 Port Holley 4150 - PFECS220

Proflow Aluminium Carburettor Spacer — 2" Thick, 4-Port, Holley 4150

Proflow carburettor spacers are a proven performance upgrade for any Holley 4150-equipped engine. By extending the intake mixture column, they improve air/fuel distribution across all cylinders, reduce fuel temperature inside the carburettor, and deliver a denser, more powerful fuel charge to the combustion chamber.

Key Benefits

• Improved Air/Fuel Distribution — Extended plenum column promotes more even mixture delivery
• Reduced Fuel Temperature — Thermal separation between carb and intake keeps the charge cooler and denser
• Power Gains — Denser fuel charge translates directly to improved combustion efficiency
• Linkage Clearance — Extra height assists with custom throttle linkage setups
• Complete Kit — Gaskets and mounting hardware included for a straightforward installation
