alright for the 1994 GSR, which o2 sensors should i get? i remember replacing my 99 civic si o2 sensors last year and they had one for "before cat and after cat". are the 1994 GSR o2 sensor just one piece? links would be greatly appreciated.

 

Your year Integra has only one O2 sensor, if you have your original cat in should be mounted on there. OBDII vehicles have two O2's.

 

thank you. my integra is obd1 so it should be one sensor, thanks for the info!
