think this one is ok?

 

the ebay ones are ok just make sure u get the right one. Back shipping is a *****.

 

Looks like this place has better prices...from pics looks like the same bosch sensors.

 

which one is the best brand?

 

bosch is OEM i believe

is the first one a good price, what does it mean by "two required"

 

I'd buy it for that price.

Probably too complicated for you.

On these vehicles, 2 are required before the catalytic convertor. Reason for 2 is because there are 2 engine banks which both create their own exhaust gases. (V6) Picture each leg of the letter V as a bank. And the reason they are required before the catalytic convertor is because the convertor will interfere with the oxygen reading, in return affecting the A/F ratio/.


The number of sensors you need to replace will depend on the SES code(s) you retrieved.


Also, it's O2 sensor, not OS sensor.

 

I have the OEM Nissan front o2 sensor you need.. brand new in package. $105 shipped. You have 2 in front, bank 1 and 2. Find out which side you need! I have both. Let me know. Paypal ready. List is $147 each. Also have rear available. Cant go wrong with Nissan direct parts! PM if interested.

the bosch universal covers both sides right?

 

Yes, both front sensors are the same (3 wires) and the rear one(behind the cat) is 4 wires.

I had to replace only one sensor but I decided to replace all so I bought them on ebay. I bought Bosch universals. I think the only Bosch they sell now is the rear one but you can get the NGK for the front , they are even better.
Here is the link to ebay seller I bought from : http://search.stores.ebay.com/GLOBAL...271212QQsofpZ0
