1-1/4 Alum Air Cleaner Spacer

The 1-1/4 Alum Air Cleaner Spacer by Racing Power Co-Packaged is a precision-engineered intake manifold component designed to elevate your engine's breathing efficiency and optimize carburetor or fuel injection placement. This aluminum spacer serves as a critical interface between your air cleaner assembly and intake manifold, allowing engine builders and performance enthusiasts to fine-tune induction geometry without compromising airflow dynamics. Whether you're upgrading a classic muscle car, street rod, or high-performance truck, this spacer addresses a fundamental tuning need: creating clearance for larger filter elements, repositioning air intake for improved velocity, or accommodating secondary fuel delivery systems.

Constructed from lightweight aluminum, the 1-1/4 inch bore diameter accommodates standard small-block and mid-range engine configurations while maintaining structural rigidity under thermal cycling and vibration stress. The spacer's compact 1.75-inch height provides measurable separation without excessive engine bay packaging conflicts, making it ideal for tight installations or when working with modern high-rise manifolds. Racing Power's manufacturing process ensures precision machining of all mating surfaces, guaranteeing leak-free gasket sealing and consistent airflow velocity across the carburetor throat—a critical factor in maintaining proper air-fuel ratio consistency and preventing stumble under acceleration or load transitions.

This component benefits carbureted street machines, vintage truck restorations, and forced-induction platforms requiring custom intake modifications. Installation is straightforward for experienced DIY mechanics: simply unbolt your existing air cleaner base, insert the aluminum spacer with appropriate gaskets on both sides, and re-secure using existing hardware. Compatibility spans most 1-1/4 inch bore carburetors and fuel injection throttle bodies; verify your specific intake manifold port configuration before purchase to ensure proper fitment and optimal performance gains.
