Sure Seal Spacer 1/2in

The ALLSTAR PERFORMANCE Sure Seal Spacer 1/2in is a precision-machined aluminum air cleaner spacer designed to optimize carburetor mounting and intake manifold clearance on small-block and mid-size V8 engines. This 0.5-inch thick spacer fits standard 5-1/8-inch carburetor flanges and provides the critical spacing needed to improve engine breathing, prevent carb-to-hood contact, and enable proper air filter fitment on modified engine builds.

Constructed from aluminum and finished in natural (uncoated) form, this spacer weighs just 0.29 lbs, making it an efficient addition to any intake system without adding measurable mass. The machined design ensures a secure seal against the carb flange gasket, eliminating air leaks that would compromise fuel mixture calibration and idle stability. The 1/2-inch height is the industry standard for addressing common hood clearance issues and optimizing the routing distance between carburetor and intake manifold on street and performance engines alike.

This spacer is essential for engine builders, hot rodders, and anyone running a carburetor-fed V8 with a tight underhood layout or recently installed forced induction or aftermarket intake components. It serves as both a practical solution to physical interference issues and a tuning tool that can influence air temperature and manifold dynamics. Serious enthusiasts stock this size as a foundational intake component for any traditional carbureted engine platform.
