I had gone to take TD of City, 6 months back, and raised same concern with the dealer. The SE told me that they are fitting some extention till Honda comes up with official solution.The even called me to see it at ASS
but I could not go.
I don't have pics, but will try to take soon.
AFA, warranty is concerned, it was denied to the owners who suffered hydrolocking due to OE placed air intake.
