5In Air Cleaner Stud 1/ 20-Apr

The 5In Air Cleaner Stud 1/4-20 is a precision fastening component purpose-built for high-performance engine builders and restoration specialists who demand reliable, corrosion-resistant hardware. This stud serves as the critical mounting point between your air cleaner assembly and intake manifold, providing a secure, vibration-resistant connection that withstands the thermal cycles and mechanical stress of both street and competition engines. Whether you're assembling a classic hot rod, restoring a vintage muscle car, or fine-tuning a modern performance platform, this stud delivers the durability and precision fit that separates professional builds from amateur shortcuts.

Manufactured from steel and finished with zinc oxide plating, the 5In Air Cleaner Stud resists oxidation and maintains its structural integrity under sustained heat exposure around the carburetor and intake area. The 1/4-20 thread pitch provides standard SAE compatibility across generations of American V-8s and small-block platforms, while the 5-inch length accommodates thick air cleaner bases and multiple gasket layers without binding. The included wing nut allows tool-free installation and removal, reducing downtime during maintenance intervals and enabling quick swaps during tuning sessions or carburetor service. Steel construction ensures this fastener won't strip under torque, a critical concern when reinstalling air cleaner assemblies that experience repeated thermal expansion and contraction.

Mechanics and enthusiasts working on Chevy, Ford, Pontiac, and Oldsmobile engines from the 1960s through 1990s will find this stud an essential replacement part for corroded or stripped original hardware. The zinc oxide finish extends service life in engine bays where moisture and salt air accelerate corrosion, making it ideal for coastal restorations and year-round drivers. Installation requires no special tools—simply thread into your manifold boss and hand-tighten the wing nut until snug, ensuring proper air cleaner seal without over-torquing. Keep a spare on hand for field repairs and future rebuilds.
