All you guys w/JDM headers and the WBC, where should i put the o2 bung? drivers or pass side? and where at on the header? Thanks Guys!

 

drivers side. as that is bank 2 on a ford

 

I gave up, some guys said drivers, some guys said passenger. Supposably the drivers runs leaner than the passenger, but couldn't get a straight answer so i put mine on the high flow cats, just after the collector , before the cat.

 

So what side did you go with? dri or pass?

 

Drivers side here

 

i put mine on the passenger because i have the wideband mountedin the glove compartment, ran it right down the kick panel, throught he grommet and out the floor.
