Hi guys,
I bought my AFX NGK WB unit around year 2009. Overall it has worked great but lately it has been acting weird at times so it was time to buy a new WB O2 Sensor again. After doing some searching on here, it seems the NTK is the better sensor over the "stock" one. I ordered one from Autozone for $69.00 this week and this is what I got (see attachments). The numbers on the box match what a NTK should be but the end of the sensor looks different and doesn't have "NTK" stamped anywhere on it.
Is this a real NTK sensor or something else? Anyone else buy on from Autozone?
Bill
