before i embark on installing my new intake, i have a few questions.

1. ls6 coolant lines- is it necessary I drain the coolant before i swap the coolant lines? i just changed the coolant last month and dont want to deal with that crap again. i do expect some coolant would leak out, but not a lot. correct me if im wrong

2. back of the the intake i got a map sensor, a big vacuum line that goes to the brake booster, and then a small vacuum line. where does that vacuum line go to (pcv system?)?

No need to drain coolant. If I remember correctly, that small vacuum goes to the AIR.... but I may be wrong.

If emissions aren't stringent where you live, now is the time to remove your AIR and EGR systems.

just deleted both systems last week.

Don't delete the little vacum line as it runs a couple of things one of which is the dash vents.

where does the other end of the vacuum line plug into?

Magic Man

It runs to a juction by the ecm and runs to a canister up by the radiator another line off it goes into cabin and I think there is a 3rd but right off hand don't remember but if you look it's a Mickey Mouse setup off the AC lines by the ecm.
