E-3225 Air filter element

When it comes to performance filtration, K&N is the industry standard. This round air filter element is constructed from multiple layers of pre-oiled woven cotton gauze protected by a mesh screen. It is designed to fit S&S Super B and Super D air cleaner housings, as well as most aftermarket aluminum teardrop and 7-inch round housings. With a 6-inch outside diameter and a height of roughly 2.188 inches, this filter provides up to five times more surface area than a standard paper filter, significantly increasing airflow while offering superior flame resistance. It is fully washable and reusable, making it a long-lasting performance upgrade for your intake.
