Optimize Your Carburetor Airflow

The Allstar Performance 4150 Shear Plate is an essential upgrade for enthusiasts looking to refine their engine's fuel delivery. Designed specifically for 4150-style carburetors, this 0.5-inch thick aluminum spacer features a precision 4-hole design with 1.75-inch bores. By introducing a shear plate into your intake tract, you effectively break up fuel droplets, promoting better atomization and a more consistent air-fuel mixture.

Key Features and Benefits

• Precision Engineering: CNC-machined from high-quality aluminum for long-lasting durability and heat dissipation.
• Enhanced Atomization: The shear plate design forces air and fuel to mix more thoroughly, improving throttle response and mid-range torque.
• Universal Compatibility: Designed for standard 4150 square bore mounting patterns, making it a versatile addition to most performance intake manifolds.
• Easy Installation: Simple bolt-on design allows for quick adjustments at the track or in the garage.

Whether you are building a street machine or a dedicated track car, managing intake turbulence is critical to extracting maximum horsepower. This spacer provides the necessary airflow conditioning to help your engine breathe easier and perform at its peak.
