So far so good. It was brutal to install drivers side of my 2010 Titan but I got it. The error code I had before is gone and noticed the truck running better. I’ve had it installed for about 2 months and no complaints. I’m giving a 4 on install. The wire length could have been just 6” longer which would have helped when leaning over the engine with my arms reaching down into the bottom of the engine. The actual install want bad once I got the rusted one off. This of course isn’t the manufactures fault.

I bought 2 of these to replace both front Fuel/Air Mixture Sensors. These look identical to the ones being replaced. I applied the anti-sieze compound on each before installing. They screwed into the socket without any problem. The connector plugged into the socket without any problems either. I reset the OBDII code and that solved the problem. I hope these last as long as the original ones (123000 Miles).

We ended up having to get 2 of these. My son and his friend were able to put them in easily. They work great. Unfortunately for us, our biggest issue was one of our catalytic converters 😭
