Well, I installed mine last night (in the freakin 97 degree heat!)
I did not use the upper part of the full length system (from MAF to TB), b/c it was not a good fit. It was like 1/2 inch too long.
Also, noticed that there was not a real good seal between the MAF and the first section of the CAI pipe. They system came with a tube of sealant that helps, but I wonder if this could loosen up over time.
Didn't know what you meant about the rubber band till I actually did the install. That was a real PITA.
Not sure yet if the filter is rubbing anything or not. I'm gonna give it a few days and then check it.
Driving, I like the performance so far. It will be interesting to see what happens on the drive home from work today when it's supposed to be 95 degrees and humid.
With my old CAI (KarKraft), these conditions caused the car to hesitate some at high RPMs. It had a metal pipe and the long
K&N filter that was only 2/3 of the way into the fender well.
