I've had this part on my car for at least a year now, but I now think I am missing something. I have the tube bolted on the throttle body without any kind of spacer, but apparently there is a spacer that goes on the TB before the hose attaches. Did everyone else get this piece? I always wondered why the inlet was so much larger than the TB w/o and kind of spacer included. I have the clamp so tight I doubt the TB connection is leaking, but think I need to call C&L now. Of course, they are not open on weekends.
