Ls1 O2 sensor? 
My 01 Ws6 has a V9G vortech superchargers and i had P0171 & P0174 lean codes. I found a major vacuum leak and a catalytic converter bolt missing which i have repaired and replaced. I decided to replace the o2's since i never have with stock Ac Delco and after doing so i seen this image in my Ls1 build book stating the one on the right is a windband o2 sensor. These are the o2's I just swapped out, are these in fact windband sensors?
