Hi guys, i'm new to my350z and i couldn't find a thread to know how to install an Aem wideband in my nissan 350z 2003. I've made a lot of research trying to know where should i put the bung for the wideband sensor but i cannot find the information. They only say put it in front of the cat, but in the z in front of the cats it's our headers ...and theres already two o2 sensors...So if you have any picture of where to install them or if you have any information that could help me plz tell me them ! Btw i'm gonna install this wideband on brand new DC Sports stainless steel headers...! Thanks everyone

 

did u ever find an answer to this iam just starting to look into getting one my self same headers too

 

Just get a set of Berk HFC's or Berk test pipes. They have the extra bung on them, ready to go.

BTW, my AEM sucks. The O2 sensor died after 1 day of use.

 

I had a bung welded in front of the actual cat on the cat pipe. My hfc had a bung after the cat, which made it worthless for a wideband.

Just make sure the bung puts the sensor at the correct angle.

I also have an Aem and its been good for about 4 yrs now.

 

Yea I want to get a dual one what wound u guys go with for it

 

+1 also in the same boat any pics on stock setup?
