I have been upgrading my 98.5 to a Banks system. In removing the turbo there was a small hose connected to the intake air side (front) it would not come off so I checked for extra play and cut it off. I thought I'd add it back onto the turbo when reassembling it. Can't find the hose anywhere, I left it attached to what ever the other end was hitched to, but I have looked and looked. Can't find this hose anywhere in the engine bay. What does this hose do? Or can I plug the hole and get along with out it?
