You don't need to use 4 O2 sensors on any header system. Moving the rears to the front positions is the preferred method with LGs.

Yep, plug the rear bungs and order adpaters from LG, so the rears will plug into the front harness. Have your tuner turn off the codes.

Default air hose

99 that also my problem, the headers I bought are from a 01/03 models so I need a dipstick tube also, I looked at the airhose I might just cut it with a cutter and get a good peice of rubber hose to hook between the 2 ends for now
