Carburetor Spacer - 4150 2in 4-Hole L/W Tapered WLS004150

A carburetor spacer is essential for optimizing manifold heat dynamics and improving fuel atomization in carbureted engines. This 2-inch tapered design provides a thermal barrier that keeps incoming charge temperatures consistent, directly improving throttle response and drivability. Whether you're fine-tuning a street engine or preparing for competition, the right spacer geometry makes a measurable difference in how your carb delivers fuel.

The WLS004150 is precision-machined from lightweight aluminum and black anodized for corrosion resistance. Its tapered bore profile reduces turbulence and promotes even fuel distribution across all four primary barrels, making it an ideal choice for 4150-pattern carburetors on dual-plane or single-plane manifolds.
