Review on Bosch 13770 Premium OE Oxygen Sensor for Compatible 2004-05 Mazda 3 Models by Scott Rao

Revainrating 5 out of 5

Works great, I recommend!

Replaced a faulty oxygen sensor in my 2004 Mazda 3 with one of these and it works great. Original. It is important to note that if used in a Japanese Mazda3 like mine the supplied connector will need to be replaced with the original connector as the notches are upside down. No tangled wires or anything, just replace the plug. I would recommend this to anyone who needs an O2 sensor.

Pros
  • An absolute legend
Cons
  • Some bugs
