My accord V6 has a variable length intake  . It changes the sound enough that it sounds like I have two VTEC transitions, one at 4000 rpm, one at 4900 rpm. |
I don't know for sure, but I am going to go out on a limb and say that with variable valve lift and cam phasing, variable intake length may not make a big difference anymore and not be cost effective.
