09-13:  this option is for all 09-13 models and 14+ models that have the AIS system removed.  We have a AIS block off plate that makes the removal easy.  Click here for AIS block off plate

14+: this is for 14+ models that have the AIS system kept in place

We recommend to remove the AIS system for better running.  There is no power difference, but your YFZ450R will run smoother/more consistent down low with it removed. We recommend a Vortex ECU to be used with all versions of the intake and especially when the AIS has been deleted.  The Vortex ECU will give you more power and response as well as better running.
