The Assault Series Hi-Flow Air Cleaner was designed to give a clean and simple aggressive look that comes with some very interesting features. This is not your typical air cleaner. With its durable clear plexiglass cover, and hidden integrated breather system, this Hi-flow air cleaner was made to stand out in a crowd. Made with nothing but innovation in mind, this Assault Series product has an even more originative feature that is sure to separate it from the rest. Every Assault Charge Hi-flow air cleaner comes with the Trask Snap in velocity stack. This Trask Assault Charge Hiflow air filter performs just as well as it looks.
