There have been no problems with stability of intake pipe, its a solid bit of kit, mine was gen 1 and does NOT attach to engine mount on the bend, no problems so far after 700 miles or so.

Forgot to add there is plenty of room for it to move/flex when it needs to as the front airbox is only attached using 2 of the rubber bungs from engine cover so it is able to move back and forth on these if needed, when I was at rolling road I could see the engine moving back n forth and looked at the silicon pipe end and it was not bending, the whole airbox/plastic pipe was just moving with engine

Hope that clears it up!
