14" round air cleaner kits are available with a premium element featuring red pre-oiled cotton gauze (washable and reusable) or a mesh-reinforced paper element – both options come in 3 and 4 inch heights. Each air cleaner kit includes a polished or black Sure-Flo base (designed for Holley 4150 and 4160 and other carburetors with 5.125" diameter neck) and all mounting hardware necessary for installation. All GM Muscle Series accessories are available in four custom finishes: natural cast, polished, satin black, and factory orange (all finishes have machined "Chevrolet and Bowtie" logos aside from polished version).
Processing & Shipping Overview
Processing occurs before shipping.
Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.
Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.
For the most up-to-date order status or lead time questions, please contact sales@smgspeed.com or use live chat during business hours.
