4150 CARB 1″ SPACER 4 HOLES AT1.75″ BORE PLASTIC PHENOLIC

Description

Enhance your engine’s throttle response and reduce heat transfer with this 1″ carburetor spacer engineered for 4150 carburetors. By increasing the distance between the carburetor and intake manifold, it optimizes airflow and fuel atomization, leading to improved combustion efficiency.

Constructed from durable phenolic plastic, this spacer effectively insulates the carburetor from excessive manifold heat. This thermal barrier reduces fuel vaporization issues, maintaining consistent air-fuel mixture density for better engine performance.

• 1″ Thickness: Provides the optimal gap to improve torque and throttle response by enhancing fuel-air mixture cooling and distribution.
• 1.75″ Bore Diameter: Matches the carburetor bore precisely, ensuring unrestricted airflow and preventing turbulence that can reduce engine efficiency.
• Four Mounting Holes: Standard 4-hole pattern ensures secure attachment to the carburetor and manifold, promoting stable operation and ease of installation.
• Compact Dimensions: Measuring 3.20 cm thick with a 16.50 cm width and height, it fits seamlessly within standard carburetor setups without added bulk or complexity.
• Lightweight Design: Weighing only 0.1 kg, this spacer adds minimal weight to your fuel system, preserving engine responsiveness.
• Brand Reliability: Manufactured by Moroso, a trusted name in performance fuel system components, ensuring quality and consistency.

This spacer is specifically designed for 4150-style carburetors, making it ideal for those seeking precise fitment and improved engine efficiency. Its phenolic construction resists heat soak better than metal alternatives, directly contributing to more stable fuel delivery under high-performance conditions.

With this spacer installed, expect enhanced throttle response and more consistent power output due to improved air-fuel mixture quality. Its exact bore size and mounting configuration guarantee compatibility and ease of integration into existing setups, reducing installation time and complexity.

Investing in this Moroso 1″ carburetor spacer delivers measurable gains in engine performance through better thermal management and airflow optimization. The combination of specific dimensions, material choice, and precise engineering makes it a critical upgrade for serious performance applications.
