Wilson Manifolds 1.00In Tappered Lw Carb Spacer 4500 2.375 Bore 24410

Increase airflow, improve throttle response, and maximize engine performance with the Wilson Manifolds 1.00" Tapered Lightweight Carb Spacer (Part #24410). Precision CNC-machined from lightweight aluminum, this premium carburetor spacer is engineered for Holley Dominator 4500 flange carburetors with a 2.375-inch bore.

Wilson's proprietary computer-generated variable-radius taper is designed to optimize airflow through the carburetor while improving air/fuel distribution throughout the intake manifold. The tapered internal design increases airflow, strengthens the carburetor signal, and helps produce measurable gains in horsepower, torque, and acceleration across the entire RPM range. Wilson states that its tapered spacers can increase airflow through the carburetor by up to 110 CFM, depending on the application.

Ideal for drag racing, circle track, road racing, marine, street/strip, and towing applications, the 24410 spacer is compatible with both gasoline and alcohol fuel systems and provides excellent performance under both part-throttle and wide-open throttle conditions.
