Hey Rusty. I am looking at the Z1 25 row right now.
I have reviewed the instructions and thought it might be possible to mount it from underneath the problem is drilling holes for the bracket.
Was also looking at the AAM R-Line but makes me wonder how effect that would be compared to the traditional air cooled. The only benefit to me is added flexibility in installation location.

For anyone that is interested - Pic of AEM and Injen filter location included.
G3 wasn't an option for me because I have Arising II front and apparently the "nostrils" might push back on the G3 filter location.
