hey i am wondering which o2 port is best for the wideband... the first one right by the turbo or the one further down by the oil pan... i leave my wideband in at all times so i want to know which will help it last the longest...

thanks... as always... for the info

The one closest to the turbo needs to be the factory one

Use the lower one for the aftermarket o2 or weld another place in for it
