Hello everyone,

I need to buy a o2 sensor (Bank 1 Rear Sensor 2) white color, OEM is kind of expensive so I try searching it online.

I found this website that have good deal with denso brand. They listed 6 of them, and I am confuse between product #1 and #5 because of lack of information...
#1 says Fits: Passenger Side, After Catalytic Converter; Car.

Location: Passenger Side, After Catalytic Converter


#5 says Fits: Car.

Location: Rear, Passenger Side

Which one is the right one? Thanks in advance.

looks like either one would fit, except #5 is the correct length, #1 you'd have to use with your old wire

 

Thanks for the respond. I just realized #5 costs double the amount of #1.
