FST has a new air filter set up that gives you almost double the filter surface area and keep the dead air box but eliminates the filter box. I has a mount at the rear of the filter to keep it in place and heat shield under it to deflect heat from the exhaust. Some other companies are coming out with an adapter for the stock air box but we think this will flow quite a bit more air. We will have pricing and jetting as soon as we complete dyno testing. These will be available at Unleashed UTV.
