TST Industries Smog Block Off Plate Kit – Kawasaki Ninja 400 / Z400

Description

The TST Emission Block Off Kit enables you to remove the air induction system (AIS) from your 2018+ Kawasaki Ninja 400 engine and seal the holes left behind.  This kit also includes a resistor plug to cap off the solenoid so that it may be removed.  With the AIS removed you will be able to get an accurate air/fuel ratio tune and keep exhaust popping to a minimum, not to mention save a little weight and decrease engine clutter.

*Removing this system may or may not still throw a check engine light, even with the bypass plug connected.
