Napa… o2 from a Z32
Or you can just drill a hole, weld on a nut and use the skinny o2 which is frmo the Z31 😉

Good Call 😉
“helps up” 2004/2005 Maxima has a 5 wire wideband o2… “same unit from bosch that 3/4 of all the company’s use for their kits”
Even just hooked up to a normal air/fuel gauge will give a way better reading then a narrowband o2…
If you can figure out how to convert the Volt Reading into an Air/Fuel ratio then you can just use a Wideband o2 + Multi Meter 😉

I have one from a redtop… not sure if that’s the right kind.
