Speedmaster PCE120.1004 2" Phenolic Carburetor Spacer, Square Bore 4 Port

The Speedmaster PCE120.1004 is a 2-inch phenolic carburetor spacer designed for square bore carburetors with 4 port configuration. Phenolic material offers excellent thermal insulation properties, helping to reduce heat transfer from the engine to the carburetor while maintaining structural integrity. This spacer sits between the carburetor and intake manifold, improving fuel atomization and throttle response characteristics in performance engine builds.

This carburetor spacer is ideal for custom engine swaps, carburetor upgrades, and street/strip performance applications where proper fuel metering and engine efficiency matter. The 2-inch thickness and square bore design ensure compatibility with standard 4-port carburetor mounting patterns, making it a straightforward drop-in solution for hot rods, muscle cars, and performance-focused builds. Phenolic construction resists warping and maintains dimensional stability under high engine temperatures.
