I was looking on Autozone's website and they list a Bosch OE type for 65 and a Bosch Universal for 60. They also list a BECK_ARNLEY
UNIVERSAL - 4 WIRE (CONTAINS SPLICE KIT) for 90. How much of a difference is there? I don't mind spending more to get something better?

Also, the previous owner removed the Cats from my car, so do I even need the 2nd O2 sensor that's located after the Cats?

The Bosch is a pretty good unit itself,personally I wouldn't spend the extra and those "universal" ones almost never fit anyways. Depending on what the previous owner did to deal with the rear cats you might need to keep them hooked up. If it was electronically done then it won't matter,if he's using MIL eliminators then you should keep them connected.

Do a forum search and you'll find that answer.

Heck, do a GOOGLE search and you'll find it.

Click to expand...

They are fancy pants resistors that regulate a voltage signal sent by the rear o2's to the ECU to fool it into thinking everything's a-OK. They prevent SES or Check Engine lights from illuminating.

I used the universals because I could extend the harness for my longtubes. They've worked great for the past year or so, but other than being longer there is no need to pay extra for them.

Just get the OE sensor from Randy Stinchcomb on here and he'll get them for about $50 a piece for ya.
