Crank Case Ventilation Ring: You will not be able to use your stock air cleaner with the Howell EFI Conversion kit. When removing your old air cleaner on most CJs and YJs you'll notice a hose that hooks into it and then hooks into the back of the valve cover. You will need to retain it so this ring will let you hook up the hose. If it's between the air cleaner and throttle body, We offer the
Valve Cover Recirculation Spacer that fits under the air cleaner and will allow you to reconnect your hose.
