Who knows? Ice in there? Getting hot coolant up there to keep the grease around the butter-fly blades in the TB soft? Those guys that designed the LT5 are probably pretty smart. There's any number of systems that could be ripped out because how/what they do is not apparent. But just like bypassing the clutch switch, you may get lucky and never find out why it's there.
When in doubt spray some "AmZoil" on it or RIP IT OUT.
