Boost Performance with Allstar Carb Spacers

The Allstar Performance Drag Hi-Flow Carburetor Spacer (ALL25984) is a simple yet effective way to increase your engine's performance. Designed specifically for 4150-style square bore carburetors, this 1-inch thick, 4-hole spacer helps improve air/fuel distribution and increases the plenum volume of your intake manifold. By extending the intake runner length, this spacer helps build low-to-mid range torque, making it a must-have for drag racing and high-performance street applications.

Technical Specifications and Benefits

• 4-Hole Design: Improves air velocity and signal to the carburetor boosters.
• 1-Inch Thickness: Optimal height for increasing plenum volume and torque.

Heat soak is a common issue that can rob your engine of power. The high-quality plastic construction of this spacer acts as a thermal barrier, preventing engine heat from transferring directly to the carburetor. This keeps your fuel cooler and denser, leading to better combustion and improved throttle response. Whether you are tuning for the track or the street, this spacer is an affordable upgrade that delivers measurable results. Find all your essential carburetor tuning components at GGCRACING.
