No problem. Just a drizzle, not a pour. I can add my 2 cents here, I think.
The air piping in this engine is quite loose and tends to rattle and buzz quite a lot once it's been removed and reinstalled a few times. It gets loose enough that at idle it can translate a lot of noise into the cabin (I thought it was my clutch going out one time it got that bad).
That could be one reason they zip-tied it like that. I did the same myself but not in that location - a little higher up close to the fuse box where there's a little black plastic tab with a hole. However the ties got a little inconvenient for services, etc...
In the end, the real vibration came from the intake opening at the front of the car beside the headlight. I put some felt pads used for furniture feet in some strategic locations and solved my buzzing intake noise problem.
Hope that helps!
