The devotees that want a leg up on the competition will find their answer in the patent-pending technology of the Comp-V High-Flow Intake System with V-Stack. This 2-in-1 system gives riders the option to quickly change the threaded V-Stack for a direct air intake or threaded billet cap to bring in air through the high-flow air filter. With significant performance gains over the stock air cleaner cover and can’t-miss head turning Two Brothers style, you’ll be the envy of your riding buddies.
