4500 Drop Base Air Cleaner by Holley®. Does your engine need LOTS of fresh air? Holley is proud to offer a breath of fresh air with our new 16x6” drop-base 4500 air cleaner assemblies and filters. The 6” assemblies are available with a red washable gauze element only. 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.
