Will rear o2 work in front?
Btw, i recall there are two brown wires on the sensor, does it matter which way they are connected or are they both the same thing?
All 4 O2 sensors for my car were the same so no point in buying any. I now have a spare O2 in case, but haven't had to use it.
Keep in mind that I went far out of my way to make sure I could reuse my O2's, I ceramic coated QTP Stainless Steel longtubes. There was speculation that perhaps the relocation of the O2's and the faster flow characteristics of longtubes were the cause of some of the stock O2 setups failing. The ceramic coating keeps the heat in the exhaust and probably offsets the relocation in my case.
