Hi all! Just picked up a 2020 LT1 this weekend, and I've been browsing the forum for the past couple of days.

I'm planning on an intake and exhaust in the near future, so I've been doing some research. In looking at the engine bay, there is a series of tubes that run from the intake to various parts of the engine. I have attached a picture and circled the tubes in question.

I know it's not the infamous sound tube, as I can see that that port is plugged on the intake and on the firewall. I'm curious as to what purpose these other tubes serve.

Lots of helpful info on this forum, but my searches for this came up blank.

Thanks in advance!

The one in front is part of the PCV system, that recycles oil and fumes back into the intake tract. You'll disconnect that one when you install your intake. The other ones are various vacuum lines for things like the brake booster.
