I have a b16a2 from a 2000 si USDM with a obd1 p30 ecu.

Which o2 sensors can i use. Do i have to use one for the 00 si or can i use one for the obd1 ecu, like 92-95 gen o2 sensor?

And is there anything wrong with buying o2 sensor that require splicing, or do i need to only buy the direct plug kind.

Thanks

 

Get a 4 wire. That's what the ecu wants at least, match the o2 to the ecu.

 

The 4 wires kind.. then i can just directly wire it in without fear of damage to ecu correct?
