I need a replacement oxygen sensor. I installed a universal one from Amazon and it did not read. My gas mileage is pretty bad with this universal one in now. So, I need to buy an OEM one.

Does anyone know where I can buy an OEM replacement online from a trusted site??
I came across a few sites not sure if they'll legit.

I knows its like 25 to 50 bucks cheaper online. Dealer sells for 205

 

We have few members/sponcers.
I bought few things from OCInfiniti. Pretty happy with service & turnaround time.

 

Ask Phil from Grubbs out in Dallas or Rick from Perry Infiniti in San Diego.

Both are active members within the forums and will give you the straight scoop on the sensors.

Unfortunately, I don't think this is an area you can trust aftermarket products. Are you positive your factory sensors are dead ? Did they throw a code ? Note that the dealer can run a series of tests on all the sensors within the emissions system and provide a printout of the results (cost about $100). I had this done when I thought the 02 sensor was the cause of my poor mileage.

In the end, my problem ended up being a vacuum leak tied to the MD spacer I installed. Seems that you need to re-torque these on a regular basis.

 

My local Infiniti parts manager sells me parts, cost + 10% or I go to Nissan when needed. When are our members going to learn not to buy crud on eBay unless it's from a dealership?
