A/C Wing Nut -1/4-20 Sp inner Knockoff Style

The A/C Wing Nut -1/4-20 Sp inner Knockoff Style from Racing Power Co-Packaged is a precision fastener engineered for air cleaner assemblies on high-performance and classic automotive builds. This chrome-plated steel component secures air intake systems with a quick-release knockoff design, eliminating the need for tools during routine maintenance or filter changes. Mechanics and engine builders rely on this fastener for its dependable clamping force and aesthetic finish that complements polished engine bays.

Manufactured in steel with a mirror-chrome finish, the 1/4-20 thread specification provides a secure, standardized fit across most air cleaner housings and tri-star mounting platforms. The knockoff-style wing nut design allows single-hand operation—spin it counterclockwise to release the air cleaner assembly without reaching for wrenches, saving time during carburetor adjustments or filter swaps. The compact profile (3.9 x 0.75 x 5.9 inches) and lightweight construction (0.19 lbs) ensure it won't interfere with engine bay clearance while maintaining the structural integrity required for vibration resistance at highway speeds.

This fastener is ideal for street rods, muscle cars, classic trucks, and custom hot rods where engine aesthetics matter as much as function. The chrome finish integrates seamlessly with polished valve covers, intake manifolds, and traditional air cleaner designs popular in vintage restorations and retro-inspired builds. Installation is straightforward—hand-tightened onto the existing 1/4-20 threaded stud, no special tools or torque specifications required, making it a plug-and-play upgrade for anyone modernizing or restoring a carburetor-fed engine.
