🚀 Walker Products 250-25005: High-Performance 5-Wire Wideband Sensor for Optimal Engine Efficiency Review

Unfortunately I waited until this week for a mechanic to install sensor 02 upstream. He installed and checked the sensor and it is defective. I have 4 days past the 30 day return period. The bottom sensor worked great.

I installed this sensor on a 2004 Altima due to an intermittent P0420 code; This is a direct fit, there were no issues with installation (mechanical or electronic) and until the code was returned (set a month).

Direct replacement for my 2005 Nissan Altima Upstream Oxygen Sensor. Even the connector and its assembly conditions were correct. Use an O2 sensor remover to remove and install the old O2 sensor. Pretty easy job for 30 minutes.

Pulled the old one out, this one in and the car (Nissan Altima 2006) idles and now runs like a champ. The old O2 sensor was causing a rough and choppy idle. Problem solved. Let's see if the gas mileage improves. The sensor is thermally protective and looks better than the regular one. Comes with extra zippers and fits perfectly.

I've searched almost every parts store and website for an O2 sensor for my car. They all said it would cost $100 to get a direct fit prewired. I want everyone to know that this product was under $100, it came pre-assembled and it fit perfectly. Thanks for a great product. Signature: A very happy customer.

product as described had all the features i need to replace the old oxygen sensor the packaging was in good condition i bought two of these products one works fine the other does not work , so I contact AMAZON customer service for warranty and they sent me a new one, I'm waiting to install it, thanks for your attention to my inquiry, good place to buy.
