Everybody likes to go fast, but not everybody likes to advertise. The S&S Stealth air cleaner kits are for the rider who likes to go fast, but wants to be just a little bit sneaky. Get all the performance of the S&S design, including the air directional "stinger" cone in the filter, and hide it under your stock air cleaner cover. We offer a line of stylish S&S air cleaner covers to go with the Stealth air cleaner. Because S&S designed the stinger section of the air filter to be a separate piece from the element, it makes the filter replacement much more affordable when the need comes to change it. The element is washable though, and should normally never need to be replaced unless it is damaged. We suggest die-hards who do longer trips in the rain to also order a rain cover. Note: S&S Stealth air cleaner kits may fit other covers using a 5/16" central mounting bolt.
