Old vs New airbox - RADE/GARAGE

Understand the difference in the old and new generation of the R/G small airbag and foam filters for R/G auxiliary tanks.
See the explanation when you have to upgrade the airbox and when not to be compatible with the current version of the foam filter with central bolt mounting.

How meny % more air Flow New vs old? I have the New one. No reason just for to know. And do you have ecumaps for 690 (mine690 enduro 2009 with Leo vince evo exhaust) for this filter??
