1.5in Air Cleaner Spacer

The MR. GASKET 1.5in Air Cleaner Spacer is a precision intake manifold accessory designed to elevate your carburetor away from the engine block, creating essential air gap for cooler charge temperatures and optimized airflow dynamics. Built for enthusiasts and mechanics seeking improved engine breathing and tuning flexibility, this spacer addresses a fundamental cooling need in naturally aspirated and modified engine builds. Whether you're running a street machine, competition carb setup, or vintage restoration, the 1.5 inch thickness provides the ideal separation distance that many experienced builders specify for maximum volumetric efficiency.

Manufactured from durable black plastic by MR. GASKET, a trusted name in performance carburetor components, this spacer features a 5-1/8 inch carburetor flange designed to match standard four-barrel carb mounting patterns. The 1.5 inch height creates a thermal barrier between the hot intake manifold and your carb, reducing fuel vaporization and delivering denser, more oxygen-rich charge into the cylinders—a measurable advantage in high-demand driving conditions. The lightweight design at 0.22 lbs adds negligible weight while maintaining structural integrity, and the black finish resists corrosion and blends seamlessly with most engine bay aesthetics.

This spacer is ideal for carburetor enthusiasts, engine rebuilders, and performance tuners working on small-block and big-block platforms with traditional four-barrel mountings. Installation is straightforward—position between manifold and carburetor, then secure with existing fasteners—making it a weekend-friendly upgrade requiring no machine work. Verify your carburetor's flange diameter matches the 5-1/8 inch specification before purchase; this ensures proper sealing and prevents intake leaks that compromise performance gains.
