Product Overview
Speedway Motors Plastic Open Carburetor Spacer – 1 Inch
Improve engine performance while keeping intake temperatures under control with the Speedway Motors 1-Inch Plastic Open Carburetor Spacer. Designed for Holley 4150 and 4160 four-barrel carburetors, this spacer helps reduce heat transfer from the intake manifold to the carburetor, resulting in a cooler, denser air/fuel charge for improved performance.
Constructed from a durable high-performance plastic material, this spacer reduces heat conductivity up to 10 times more effectively than aluminum, helping minimize fuel temperature and improve throttle response. The open-plenum design promotes increased airflow, making it an excellent choice for circle track racing, street performance, and other high-performance applications.
This spacer is IMCA approved for use with 602 and 604 Crate Engine Northern Sport Mods and Modifieds, making it a trusted choice for racers looking to stay compliant while maximizing performance.
