Small Air Cleaner Wing Nut

The Racing Power Co-Packaged Small Air Cleaner Wing Nut (R2181) is a precision-engineered fastening component designed for secure air cleaner assembly on carbureted and fuel-injected engine applications. Manufactured from steel with a chrome finish, this 1/4-20 thread wing nut provides reliable hold-down capability while offering ease of hand installation and removal without specialized tools—critical for routine engine maintenance and carburetor servicing.

The 1/4-20 thread pitch is the industry standard for most aftermarket and OEM air cleaner assemblies, ensuring universal compatibility across applications. Chrome plating provides corrosion resistance in engine bay environments where moisture and temperature fluctuations accelerate rust formation on bare steel fasteners. The wing nut design allows for hand-tight fastening without requiring wrenches or sockets, reducing installation time during intake modifications, filter changes, or carburetor work. Weighing just 0.06 pounds and measuring 3.9 x 0.65 x 5.95 inches, the compact form factor fits within tight engine compartment spaces without interference.

This fastener is essential for engine builders, hot rod enthusiasts, classic car restorers, and anyone performing carburetor or intake system work. Racing Power Co-Packaged components are widely specified in performance automotive applications where hardware reliability directly impacts engine reliability. Whether rebuilding a traditional carbureted engine or upgrading an air intake system, a quality wing nut prevents vibration loosening and loss of air cleaner sealing—both critical to engine efficiency and proper air filtration.

Available individually, this small air cleaner wing nut serves as a replacement or spare hardware component in engine maintenance kits and carburetor assembly projects. Its proven chrome-plated steel construction has become the standard fastening solution in automotive service across decades of engine rebuilds and performance modifications.
