The steel pulleys offer OEM strength and durability, and come with a lifetime warranty having been designed and tested by SHM engineers.
Cold air kit mounts in factory location, compatible with most aftermarket strut tower braces. Features a 114mm mass air meter housing and a lifetime reusable filter. Also included with this package is SHM’s professional grade pulley puller, which is the best way to remove the stock supercharger pulley, without damage to the supercharger.
