Maximize Airflow with Allstar Performance 4150 Carb Spacers

The Allstar Performance 4150 Open Carb Spacer is a critical component for drag racers and engine builders looking to optimize intake charge and increase plenum volume. At 2 inches thick, this open-style spacer allows for better air-fuel mixture distribution, which can lead to improved throttle response and increased horsepower in high-RPM applications. Designed specifically for 4150-style square bore carburetors, this spacer is a simple yet effective way to tune your engine's performance.

Key Features

• High-Flow Design: Open plenum design helps maximize airflow and intake charge efficiency.
• Durable Material: Constructed from high-strength, heat-resistant plastic to minimize heat transfer from the intake manifold to the carburetor.
• Precision Fit: Designed for standard 4150 square bore mounting patterns.
• Lightweight: Ideal for drag racing applications where every ounce counts.

By installing this 2-inch spacer, you effectively lengthen the intake runner, which can shift the power band to better suit your vehicle's specific needs. The durable plastic construction acts as a thermal barrier, keeping your fuel cooler and denser for a more efficient burn. Whether you are fine-tuning your drag car for the strip or upgrading your street/strip engine, this Allstar Performance spacer is a reliable and cost-effective upgrade.
