I remember reading that smebody found the same oxygen sensor our car uses, but with a different electrical connector. My fuel mileage has gone to pot, so I think I need to change my sensor, but alas the porsche one is way too much $$$. So does anyone have any details on which sensor to buy and splice in?

Thanks!

Bosch makes a replacement, just doesnt have the stock connectors. Cut and splice works fine. I do not have the Bosch p/n but any Autozone can look it up for you.

BTW - Bosch also makes a stock replacement with connectors but it is certainly more.

I just did that last week. The sensor is from Import Parts Authority (http://www.importpartsauthority.com) part #13953 for $39.62. Spliced the wires and it works fine! Also search for it at Vertex Auto - that how I found the part number.

Hope this helps!

89 ford taurus 3.0L is pretty much the cheapest at $35 in any autozone. Screws in, plenty long enough to splice, and works great. Most of the time it's the connectors or wire length that change the price.

On time (at band camp) on my mustang I went to buy new sensors. Stock sensors were in the $85 range. Since I had long-tube headers I needed ones with 6" longer wires which were $45. Same sensor, same connector, 6" more wire and I saved $40 each. Amazing what they pull these days.

RX7 sensor is 137 dollars, it is the same as an old Dodge Omni, cost from my supplier is 15 bucks.

I was just searching on this topic last night and came across some interesting discussion about how to splice it in (and whether to use Bosch 13913 or 15725 -- Paragon has them). Here's one of the more helpful threads I found: thread.

My recent O2 sensor came with the crimp splice connector.

The whole breathing through the wire thing sounds like snake oil to me. How could Bosch cut the wires without blocking off the "air passage.'

I was so intrigued by this that I just took apart an old one. Hear are my findings.

1. Bosch wires are crimped on both ends, a magnifying glass revealed that the wires are cut, (self sealed) and do not appear to be hollow.

2. When people figure out that they can save over one hundred dollars on a commonly replaced item, it's time for some rumors.

3. O2 sensors are not that complicated.


note the heating rod

crimped ends

that's all there is to it

I forgot to add that there was a piece of shrink tubing that went over the bare crimp connector. suffocates those itty bitty electrons!

I just realized that my car has the california emissions package... does this change anything, or will the universals still work? I dont live in California any more, but was the computer calibrated specifically for california cars?

The only diff in the Cali cars is pre-85.5 where 1-wire units for 49 states were changed to 3-wire (preheated) for Cali models.

The simple answer to this question of O2 sensors is to get the 3-wire Bosch universal 13913 w/o connector kit or 15725 w/ connector kit. The importance of the connector kit is a subject of debate, and is not our place to say how effective it is. Some folks have in fact contacted Bosch NA and asked for a specific explanation - that's their version, but at least it's an official company stance. The connector kit is basically a late model GM tight lock system - keeps it safe from water damage, etc.

Good Luck!
