Kit comes with a standard size classic S&S teardrop cover, in a Lava Chrome (black chrome) finish that leverages the mirror finish of traditional chromium and gives it a smoky radiance producing a unique dark look. Includes a High-Flow filter element and an air directional stinger cone to guide the flow of air as smoothly as possible into the engine. Note: This filter can optionally be be used with the stock air cleaner cover, for a true stealth mode, but 558651 adapter is required when installing the OEM air cleaner cover.
