The Edelbrock Nut - Air Cleaner 2-1/8 Dia. Black Anodized (Part #4271) is a precision-engineered fastening component designed for carbureted and fuel-injected engine air cleaner assemblies. This 1/4-20 inch threaded nut serves as the critical securing element that holds aftermarket air cleaner housings firmly in place, preventing vibration-induced loosening and ensuring consistent carburetor or intake manifold sealing during engine operation.
Constructed from aluminum with black anodized finish, this nut delivers corrosion resistance and a professional appearance under the hood. The 2-1/8 inch diameter base provides a wide clamping surface that distributes force evenly across air cleaner mounting surfaces, reducing the risk of cracking or warping on plastic or composite components. The 1/4-20 thread pitch is standard across most carbureted and modern fuel-injected applications, ensuring broad compatibility with Edelbrock air cleaner kits and OEM replacement systems. The anodized finish protects the aluminum from oxidation in the underhood environment while maintaining the signature Edelbrock aesthetic.
This replacement nut is essential for engine builders, restoration specialists, and performance enthusiasts installing or maintaining Edelbrock air cleaner systems on small-block and big-block V8 applications, LS-platform vehicles, and classic muscle cars. Whether replacing a stripped fastener from a previous installation or ensuring you have OEM-correct hardware for a complete carburetor rebuild, this nut guarantees secure, reliable mounting without the need for secondary safety measures or improvised hardware solutions.
Edelbrock has established itself as a trusted name in intake manifold, carburetor, and air cleaner engineering for decades. Specifying genuine Edelbrock fasteners ensures that every component of your air induction system meets the manufacturer's original torque specifications and dimensional tolerances, preserving carburetor calibration and engine breathing efficiency.
