The Edelbrock Carburetor Spacer - 1in Open - 4500 is a precision intake manifold accessory engineered to optimize fuel distribution and engine breathing in high-performance applications. Designed for serious tuners and engine builders, this one-inch open spacer increases the distance between the carburetor and intake manifold, allowing cooler air to flow through the engine bay and improving throttle response. The spacer's design fits carburetors with Dominator flange mounting, making it ideal for street performance, bracket racing, and custom engine builds where incremental gains in intake charge temperature and manifold velocity matter.
Manufactured from aluminum and finished in natural bare metal, this spacer features a lightweight yet rigid construction that withstands high-flow applications without flex or degradation. The one-inch thickness creates a thermal barrier that keeps intake charge temperature lower, reducing detonation risk and allowing for more aggressive ignition timing or boost in forced-induction setups. Gaskets and hardware are included, simplifying installation and ensuring a leak-free seal at both the carburetor and manifold interfaces. The open design—unlike restrictive designs—maintains full flow characteristics while delivering measurable improvements in power delivery across the RPM band.
This spacer benefits engine enthusiasts running Dominator-flange carburetors on naturally aspirated or supercharged small-block and big-block platforms. Installation is straightforward: remove the existing carburetor, bolt the spacer to the manifold using the included hardware, and remount the carburetor on top. The compact footprint (7.85 x 1.55 x 8.65 inches) and modest weight of 2.03 pounds ensure minimal impact on underhood packaging or engine bay balance. Whether you're tuning a street rod, circle-track racer, or hot rod engine, the Edelbrock Carburetor Spacer - 1in Open - 4500 delivers proven thermal and flow benefits that professional builders have relied on for decades.
