So I need O2 sensors for my 2006 special value aveo (possibly a catalytic converter too)
Can anyone point me in the right direction in buying the O2 sensors (upstream and downstream)? Thanks.

I believe a large majority of the time it's the upstream sensor that goes bad, and replacing it takes care of the problem. Are you getting codes or other performance data that showing problems with both sensors and the cat as well?
AFA buying goes, I'm not aware of a specific O2 sensor which doesn't work ok on our Aveos - maybe someone else here has had problems and will post about that. Assuming none are bad, then just go for the best price. There can be quite a large difference on the various sites and stores. Earlier this week I paid $47 shipped for an O2 sensor for our Dodge Caravan from a popular online store. This sensor had a range of prices elsewhere, all the way up to $74 (same make/part #).
It would be much better if they only used one way to describe these sensors, but I think the various descriptions are as follows: upstream=front=before cat=in front of cat; downstream=rear=after cat=behind cat. The other issue is universal versus "exact fit". Universal might require cutting/fitting wires, and in some cases may not work at all in some vehicles. Exact fit should always be just that - plug and play. Surprisingly, exact fit sometimes cost less than universal
How many miles on your Aveo? Are you seeing recent performance problems? Personally, I wouldn't consider changing an O2 sensor unless there is a code, or performance issues that might point to that sensor. One helpful indicator is gas mileage. I keep track of MPG, and would start to think about things like O2 sensors if it began to go South. Skipping or hesitation is another big red flag.

Well here's the deal the car has 145k miles (3/4 of them highway) and the check engine light came on about 15k miles ago. The car won't even pass inspection right now because the tires need to be replaced and the check engine light is on. My dad said he would let me have the car if I got it street legal again, so I'm trying to spend as little as I can to do this...He said when he took it to the shop it came back with O2 sensor errors, anyways I found them on autorock for 35 bucks a pop and it says they fit upstream and downstream.
Ok, now replacing the sensor makes sense. But, you should just try the upstream sensor first because that usually solves the problem. Based on what you wrote, I assume you're looking at the APWI 4413. They don't say how long the wires are, but they must be at least 16" in order to fit upstream. But if they're much longer you might have to cut/splice in order to avoid the wire hanging free and getting cooked. Maybe someone else can chime in about how the quality of this particular sensor might be.
Hey Guys well for knowing the best place of buying O2 sensor must visit that url:
