6in Air Cleaner Stud & Nut

The 6in Air Cleaner Stud & Nut from TRANS-DAPT is an essential fastening component for securing air cleaner assemblies to engine intake manifolds and custom air intake systems. Designed for automotive builders, restoration shops, and performance enthusiasts, this stud accommodates the need for reliable, corrosion-resistant hardware in engine bay applications where vibration and thermal cycling demand superior holding power. Whether you're assembling a classic hot rod, modernizing a vintage engine, or building a custom intake setup, this component provides the secure foundation your air filtration system requires.

Manufactured from steel and finished with zinc oxide plating, the 6in Air Cleaner Stud & Nut delivers corrosion resistance and durability in both street and competition environments. The 1/4-20 thread specification ensures compatibility with standard metric and domestic engine configurations, while the 6-inch length accommodates tall air cleaner boxes and custom fabricated intake systems common in street rods and modified engines. The included wing nut provides tool-free assembly and disassembly—critical for quick access during maintenance, tuning, or filter changes. The zinc oxide finish protects against moisture and salt exposure, extending service life in harsh storage conditions or coastal climates.

This stud is ideal for hot rod builders, engine rebuilders, and mechanics installing performance air intake systems where OEM fasteners are unavailable or incompatible. The 6-inch length makes it particularly suited for tall aftermarket air cleaners, custom manifold designs, and applications requiring extended standoff distance between the filter assembly and mounting surface. Installation is straightforward: thread the stud into the intake manifold boss, position your air cleaner base, and secure with the included wing nut. Mechanics appreciate the replaceable design—if a stud becomes stripped or damaged during service, this affordable component can be swapped without removing the engine or intake assembly.
