The Spectre 1 inch carburetor spacer is a universal adapter for Holley, Edelbrock or AFB carburetors, built with a precision die‑cast aluminum outer plate and heat‑insulating phenolic material to reduce heat transfer. It comes with both an open spacer insert and a four‑hole insert so you can choose the airflow characteristic you prefer, and includes gaskets and installation hardware for a straightforward fit while helping raise air/fuel velocity into the intake.
