They are vacuum lines. They go into a hard metal line if you follow them down, which runs inside the curve of the intake manifold to the timing betl side of the motor. There they plug into an emissions sensor (having to do with the evap canister.) The one that your finger is on runs into the birds nest of emission lines by the firewall, goes through a pcv valve, and ends up attached to the evap canister itself. They takes fumes from the charcoal canister absorbed from evaporated gasoline and put it into the engine to save the whales.

The coolant lines are on the other side of the throttle body, on the bottom. You can see them coming off the water neck and water pipe, but on the bottom.

I was going to say the same thing, going to the charcoal canister.

The 1g has these lines connect to the intake track right after the MAF. They made it easier to reach it for the Smog people I guess Cali smog stations are checking the evap system now with a new machine. They keep adding more and more tests.
