Does Volant make an enclosed system for the 06 X? I am picking up my OR X tomorrow and I asked the dealer about the Nismo and they said that it is an open element type and that if water were to get in to the engne via the intake it may void the warranty of sorts. How likely is this with the Nismo versus an enclosed system I assume the open element is more susseptible to the "elements". Would love to hear anyones thoughts on this. Is it really worth the extra $?
