SHLPDFM Carburetor Spacer 1in Phenolic Adapter for 4‑Barrel Holley

Description

Product Overview

The SHLPDFM carburetor spacer is a 1‑inch thick phenolic adapter engineered for 4‑barrel carburetors with a square bore base, such as Holley 4150/4160, Barry Grant, Carter and Edelbrock models. Made from high‑temperature phenolic resin, it provides excellent insulation, reducing heat transfer from the intake manifold to the carburetor. The open‑design increases plenum volume, while the four‑hole configuration accelerates airflow for better low‑speed torque. Package dimensions are 6.81 x 6.73 x 1.65 inches and the unit weighs 1.08 pounds.

Usage

Ideal for street performance, drag racing, and off‑road applications, this spacer fits small and big block Chevrolet, Ford and Chrysler Mopar engines. Install it between the intake manifold and carburetor to gain a noticeable boost in throttle response and overall engine efficiency. Perfect for enthusiasts seeking a simple, cost‑effective upgrade without extensive modifications.
