Post-cat O2 sensors

[landrovered]

It does not require a special tool, it is butt simple as long as you remember to unplug the sensor before you try to remove it. Also - DO NOT PUT ANTISIEZE OR SEALER on the sensor when you re-install, the chemicals can contaminate and ruin the sensor.

It is not a difficult job...the only 1 i had trouble with was the post-cat, passenger side ..... it's a tight spot and the wire and head unit have to find their way around a number of obstacles.
I would recommend getting the right wrench as it may be frustrating to do otherwise. Try Harbor Freight is you have one local, or since it is only 1 wrench just go to Sears.

Just finished. Pretty easy. Crescent wrench worked fine, BTW.

How many oxygen sensors does a 97 boxster have? .... qty4 I assume....right?

How many wires do they all have coming out of them?

I found some universal ones for $20-$30 but not sure which ones I need specifically.

I believe the 1997 has four as well.

There are four wires coming out of each.

Here's some links that might be helpful:

You can also just do a "Search" for oxygen sensor on this forum.

WOW. I just took her for a 15-20 mile down the highway with the new sensors installed. I really didn't think replacing just the post-cat O2 sensors would make much of a difference in performance, but WOW. The subtle hesitation (and it was subtle...easily ignored) is gone. She was chompin' at the bit, just raring to go, and go she did. Had to watch myself (as well as watching for brake lights in the distance!)

so..... the cheapo $30 on Partsbin.com can be spliced into a 1997 boxster for sure?

I was reading stuff about some hollow tube around the wires that cannot be blocked or something?.....or does this not apply to the older boxsters

How many people have used the O2 sensors that need to be spliced in with good results?
