bosch o2 sensors

[tiffo60]

a guy on nloc is selling a couple of these bosch sensors part number 13117, are these the right ones to replace the front sensors on our trucks?

if they dont have the factory plugs on them i wouldnt get them. Soldering is the only way to cut and play with o2 sensors and its a 50/50 shot that you wont have a problem. Atleast thats my experiances....
