K&N Air Filters - 3800 Universal Exhaust Continue to tighten the rockerThe 99+ airboxes are much better than the 97 98 fender draw units. As a budget solution to a Wizair box you can run a K&N drop in air filter in your 99+ style airbox with good results. We offer the drop in for the 97 98 model GP but do not recommend going that route because, the 97 98 GP air box is blocked from cool air by the factory coolant bottle. You could either pick up a used 99+ airbox and 99+ coolant bottle or get our ZZP or Wizair intake. All
