I'm going to need to redo my O2 sensor soon. Just from looking at the NAPA site, an OEM replacement is $129 and a Bosch universal is $57.49. What's involved in getting the Bosch to fit?

 

The bosch universal will come with pretty good instructions. You cut the plug and wire near the point where it comes out of the sensor, to preserve the legnth of the wire. Then Bosch supplies a crimp connector to connect the wires, and a heat activated shrink protector to cover the connection. Alternativley, you can sodler and tape the connection and use the shrink protector. Save your money, buy the universal sensor, the only difference is having to attatch the plug yourself.
