Overview
Holley is proud to offer another breath of fresh air with our new 16" drop-base 4150 air cleaner assemblies and filters. Available in 3", 4" or 6" filter heights and in chrome or EDP black. The assemblies are available with a red washable gauze element or a white pleated paper element to offer the look you have in mind. The tops are so large and smooth we decided to leave them plain for a nice stealth look, or to use as a canvas for creating your own look. They feature a 15/16" drop-base so hood clearance is gained above without creating clearance issues below.
