Edelbrock 8710 Carburetor Spacer 1 Inch Open Center Phenolic Square Bore

The Edelbrock 8710 Carburetor Spacer features an open center design used to add more plenum volume or increase the distance from carburetor to plenum floor. This spacer allows you to position your carburetor above the intake manifold flange to improve airflow characteristics and enhance overall engine performance.

Key Features:

• 1-inch thick construction made of black phenolic plastic
• High-tech phenolic plastic material provides excellent heat insulating properties
• Open center design ideal for single-plane intake manifolds
• Square bore mounting pattern fits 4150/4160 style carburetors
• Withstands extreme temperatures and dampens reversion effects on the carburetor
• Includes mounting hardware and gaskets

Applications:

Compatible with Holley, Edelbrock, AFB, Carter, Quick Fuel, ProForm, and other square bore carburetors and throttle bodies. The open spacer design is particularly effective when additional plenum volume is needed or when optimizing carburetor-to-manifold distance for improved performance.

Benefits:

Spacing your carburetor above the intake flange increases plenum area for more top-end torque and horsepower. The phenolic plastic construction provides superior thermal insulation compared to aluminum spacers, helping to keep fuel cooler and reduce the risk of heat soak and vapor lock in high-temperature applications.
