Im about to purchase and AEM wideband set up, guage and 02 sensor. my question is could i just buy the guage and tap it into my current o2 sensor or do i need to buy the kit that comes with guage and its brand sensor. sorry if this is a stupid question. my car is 95 civic with b18b1 obd1. thanks

 

the gauge wont work with a stock narrowband o2. the connectors are different as well.

 

you need the whole kit.

 

Thanks Alot!!!
