If you've got a normally aspirated IFZ, odds are good that some day you're going to want another one of these tubes.. as they do tend to crack in time, particularly if you've been a little aggressive with the air filter changes. This came out of a '97 Collector's edition, so it's got the upgraded rubber and extra sound dampening..
ok, not really. It's a solid tube though, how about $40.
