Air Cleaner Stud Kit - 5/16 x 3.200 S/S

The Air Cleaner Stud Kit - 5/16 x 3.200 S/S (MPN 400-0303) is a precision fastening solution engineered for intake manifold and carburetor assembly work on classic and modern engines. Whether you're rebuilding a vintage small-block, restoring a muscle car, or upgrading an air intake system, these stainless steel studs provide secure, corrosion-resistant fastening where standard bolts fall short. This kit addresses a critical need in engine modification: reliable, long-lasting hardware that withstands repeated disassembly cycles and resists rust in high-temperature intake environments.

Constructed from 300-series stainless steel, these studs offer superior corrosion resistance compared to zinc-plated hardware, making them ideal for both street and performance applications. The 5/16-inch diameter and 3.200-inch length are sized to accommodate standard air cleaner base plates, intake gaskets, and manifold mounting points across a wide range of engine platforms. Stainless construction eliminates galvanic corrosion when paired with aluminum components and reduces thread galling during installation—a major advantage over inferior fasteners that seize or strip under thermal cycling.

Mechanics and enthusiasts restoring carbureted engines, converting to modern fuel injection, or performing intake work will find this kit indispensable for leak-free, professional results. The stud design allows precise spacing and alignment of air cleaner housings without the risk of cross-threading that plagues bolt-only assemblies. Compatible with most 5/16-inch threaded bosses on intake manifolds and carburetor mounting flanges, these studs are a must-have for any serious engine bay rebuild.
