Description
If you're looking to drop some weight from your Kawasaki Ninja 400, Z400, or Ninja 500 and help get the most accurate air / fuel tune, ditching the air induction system is the right move. This emissions block off plate caps the AIS system to prevent uncontrolled secondary airflow and enabling you to accurately fine tune your Kawasaki. We include everything you need to accurately and correctly remove the system. We include the CNC machined block off plate which features a durable black anodized finish, rubber plug, and PAIR AIS Eliminator Circuit plug which prevents your Kawasaki from displaying errors. All of these components create an easy to use kit that completely removes your stock Kawasaki AIS system.
