Wish I could help but sure someone on this forum can help. If not, take it back to your Scion service center. Should take them about 10 seconds to help you.

Might as well get used to it. I believe it regulates vacuum and is noisy as all heck. I installed a rubber grommet to reduce the noise. It does help. Stock intake is plastic. You now have it attached to metal that sends it into the passenger area.

 

Vacuum Switching Valve. Do your best to insulate it with rubber/ foam. It's a problem with 90% of aftermarket intakes, so don't be too concerned. After all, you wanted your car to be louder ;)

 

yep the loud a$$ ticking is normal.
