Cell Foam 3in x 6in x 16in (1pc)

The Cell Foam 3in x 6in x 16in from RCI is a purpose-built fuel cell safety foam designed to prevent fuel sloshing, reduce fire hazard, and protect your engine bay during high-performance driving or racing operations. Whether you're building a dedicated track vehicle, upgrading a hot rod, or engineering a competition platform, this foam insert serves as a critical safety component that meets the demands of serious automotive enthusiasts and professional mechanics. Fuel cell safety foam has become essential in custom builds where fuel tanks are relocated, modified, or subjected to extreme cornering and acceleration forces.

Cell foam works by filling internal tank voids and creating a barrier matrix that absorbs and stabilizes fuel movement, significantly reducing the risk of fuel starvation during acceleration, hard braking, or sustained cornering. The 3-inch width, 6-inch depth, and 16-inch length dimensions provide substantial coverage for mid-sized fuel cells commonly found in street rods, muscle cars, and race platforms. At just 0.4 lbs, the foam adds minimal weight penalty while delivering maximum safety redundancy—a critical trade-off for builds where every tenth of a pound and every safety margin matters. The closed-cell structure resists fuel absorption and maintains structural integrity across temperature cycling and prolonged fuel exposure.

This foam insert is ideal for fabricators and mechanics retrofitting aftermarket fuel cells, building competition vehicles, or upgrading legacy fuel systems to modern safety standards. Installation is straightforward—cut and fit the foam to match your tank interior geometry, securing it with fuel-safe adhesive or mechanical fasteners as needed. Verify tank dimensions before purchase to ensure proper fit; the 16-inch length accommodates most standard horizontal fuel cell configurations. RCI's Cell Foam has earned recognition in the fabrication and racing communities for reliability under sustained high-G environments, making it a trusted choice for shops and enthusiasts committed to uncompromising fuel system safety.
