before cat, left and right...walker, denso or bosch?

 

i bought walker, even though it was for the rear one. Seems fine so far.

 

how many miles?

 

about 5k so far. Unless you hear any horror stories, I don't see how one could be that much different from the other.

 

i bought walker

 

I heard bosch o2 sensors are really good

 

Anyone have denso?

 

bosch
10char

 

bosch also for the cat

 

i bought them from the dealer... you pay more, but they usually are the best choice

 

walker, been 8k or so no problems for the front two

 

who make the oem o2 sensor for nissan?

 

should the sensors b replaced even though theres no error codes on them from the ecu? im riding on 161k and about 350 miles to the tank on the original sensors?

 

nope, they should definitely throw a code if they're bad. They might be starting to go bad, but your mileage doesn't look too horrible.

 

The rear sensor has nothing to do with the air/fuel ratio so it won't hurt your gas mileage even if it dies completely

I bought the Walkers from the group deal

 

Walkers will work fine, go ahead an save some money.

 

i Bought a Denso a while back it was like $86 online

 

oxygensensors.com...$60 or so

bosch is an OEM of O2 sensors to all of detroit, and most any domestically built car.....their spark pluigs are crap, but they make a nice quality sensor.

The heated O2 sensors in Max's (three wires), don't require routine replacement like the old single wire O2 sensors did....wait for a code.

 

I just bought the O2 sensor for the b-pipe. My old one was welded to the stock b-pipe when I got exhaust done today. Too lazy to put it in right now.

Nissan Dealership: $174 after tax

 

I replaced mine last time with a Bosch. Seximagtr replaced his with a Walker and hasn't had a single problem If any of my others go out I'll use Walker since they are cheaper and nobody has had a problem out of the ordinary.
