Bosch 15525 Premium OE Fitment Oxygen Sensor - Compatible With Select Infiniti FX45, M45, Q45; Nissan Altima, Maxima, Murano, Quest, Sentra, X-Trail

This is an exact fit replacement for the rear mounted o2 sensor for my '05 altima. Just unscrew the old one and install the new one. An o2 sensor socket makes this a much easier job. Good quality, no problems and much cheaper on amazon than the auto parts store.

This was apparently the OEM replacement for the 2004 Nissan Murano. I got a P0420 code and replaced it in about 20min by removing a bracket for easy access. In about a week my check engine light went off, after an idle relearn sequence I was in business!

My'05 Nissan Altima had the CEL on for quite a while. The error code was P420 which is a common code for that generation of Altima. Unfortunately that code is very vague. It could be anything between a vacuum leak, bad O2 sensor, or a bad catalytic converter. Based on the fact that I have 130k miles on the car, I went after the oxygen sensor first, being that it is relatively inexpensive and an easy fix. After 6 weeks and 1k plus miles, the CEL light isn't on anymore. I've noticed a slight improvement of fuel mileage too, maybe 1-2 mpg. Based on the research I did online, most shops will try to get you to replace the catalytic converter first. That is an expensive fix. I would recommend fixing the O2 sensor first. The Bosch model was well made, and probably a bit better quality than you would get from a discount parts store.

excellent quality and price OEM fit

Arrived on time and fit perfectly. I was a little hesitant as the product came in an envelope with the factory box flattened and shoved inside, however it worked perfectly. Took a little while to remove the old one, so if you need help let me know and I can tell you how I did it. Works perfectly!

No funcionó

Good quality product..... Exact fit.. the shipping was very late.. took 4 days, no the 2 days shipping that days offer!!!

it not fits my car the cable too short i checked before i purchase this item on the page it say fit on my car,i did not install right away till today the date is 12th of december i was going to put o2 sensor on came to find out the cable is too short.

Perfect fit with no issues at a fraction of overpriced auto parts stores.

The car had error code P0037 and installing this sensor solved the problem so far, after one week (200-300 km). Hope it does not return. However, it is too soon to judge the quality or the fuel consumption changes.

This product was touted to fit my Murano 2003, the lead was too short to fit in the clips, then the ECM showed it as faulted, and there is no-where to find warrantee or return information on Amazon. I like the one off Ebay a lot better, it fit and worked.
