Replacing B1S1 O2. Need some pictures
Hey guys,
Attempting to replace my B1S1 O2 sensor myself and need some pictures if possible. Been searching through the forums for hours but no pictures or diagrams. I know its pre cat pass side but dont know if im looking at an egt or o2. Any help would be great, even just a link. Also best place to buy ? ECS most likely? Thanks again

Take your covers off (its helps a little) and look between the engine and firewall. The wires for the O2's are on the passenger side firewall just above the valve cover. Follow them down and you'll see the O2 sensor just sitting there.
I bought a 3' 1/2" extension from sears and was able to get it loose from the top side of the engine.
