couple of quick questions regarding jdm b16 o2 sensors.

1) i'm putting in a dc sports header, which only has one o2 sensor bung. should i have a bung for the secondary sensor put in just behind the headers?

2) is there any difference between the primary & secondary sensors themselves? (other than the obvious difference in the wiring plugs) i'm thinking that given how much fun o2 sensors can be to remove, i'll just get two new ones.

thanks,
Eric

 

get a good muffler shop weld in a second bung
(near/or as close to) the stock location on the DC header....

Ok, on the headers themselves - much easier as I can do that before the headers go in.

What about any differences between the primary & secondary sensors? Can anyone tell me if they're the same or different?
