Angled Carb Spacer 4150 2in 4-Hole Tapered

The Angled Carb Spacer 4150 2in 4-Hole Tapered by Wilson Manifolds is a precision engine component designed for carburetor-mounted applications requiring optimized intake manifold geometry. This spacer elevates the carburetor away from the intake manifold surface, creating critical air and fuel flow pathways that improve distribution across all cylinders. Built for serious street and performance builds, the angled configuration enhances throttle response and idle quality by promoting laminar fuel charge movement through the runner system.

Engineered for the 4150-pattern carburetor flange, this spacer features a tapered bore design that acts as a transitional flow guide from the carb throat to the manifold inlet. The 2-inch height is the optimal sweet spot for most applications—tall enough to create significant plenum volume and insulation from engine heat, yet compact enough to maintain hood clearance and avoid carburetor float bowl complications. Precision machining and durable construction mean the spacer maintains integrity under varying fuel types, ambient temperatures, and extended use cycles.

This Wilson Manifolds spacer suits builders and enthusiasts upgrading carbureted engines where intake efficiency is crucial. Whether you're tuning a classic muscle car, street rod, or modern performance engine, this spacer delivers measurable gains in atomization and combustion efficiency. The four-hole mounting pattern ensures secure bolt-down compatibility with standard carburetor and manifold interfaces.
