Ninja 400/Z400 - Modifying Airbox to fit the velocity stacks - more details

**Attention you MUST do this before attempting to install the velocity stacks*
If you purchased complete turn key, ready to install Airbox this video does not apply.
This video explains more in depth and clarity that you “must” open up the holes in the Airbox larger to allow expansion of the OEM cut down grommets, throttle body intake boots or velocity stacks (whatever you choose to call them)

I 3D printed a velocity stack and it's attached to my inlet hose (Cut past the air resistance portion) aimed at the deepest cold part of the Fender. Using a AEM DRYFLOW drop in and Airbox covered with anti heat tape.
