I have a 94 civic ex with a 95 integra ls swap.. My check engine like came on and we determined it was the o2 sensor.. my question is 1) when i get a new sensor do i get one for a civic or the integra?? and 2) do i install it in the headers or the cat? Appreciate the help...

 

either one will work fine.. you just need a 4 wire o2.. and you have a header not headers
just grab a 7/8 wrench and take the old one out and put the new one in

 

Get an NTK 24172 O2 sensor, the wire's gonna be a little longer but that's easily tucked away. It only costs $48 plug and play no splicing required from http://www.summitracing.com i have one on my 94 civic ex works great; the applicatiopn specified for my engine fom NTK was $40 more for jsut a shorter wire.

 

i have a good used oem one for 30 shipped

 

thanks for all the help folks! i think im just gonna get a new one from summit. thanks for the link
