Anyone have experience with ebay aftermarket oxygen sensors? Looking to buy some

[bertrenolds]

Obviously oxygen sensors are pretty expensive but I found a set of upstream and down stream sensor for $25 a set for my 2002 audi allroad, should I be concerned? Here is the link They look like the denso sensors but obviously they are not. should I avoid theses and just buy bosch sensors or what? Or are oxygen sensors all the same?

That is cheap!

Given the cost of gas and the difficulty associated with installing them I would stick to Bosch for the upstream.

These cars have the narrow band, switching style O2 sensor sirs which can probably be manufactured for cheap but the upstream sensor is used to zero in fuel efficiency so you want one that works well.

Never go eBay parts unless you want to deal with eBay part problems.

After my experience with expensive - but not Audi - suspension parts failing after a year which I bought from a "reputable" site, I'd be wary of super cheap parts on eBay.

I've tried ebay sensors and had nothing but problems. The heaters keep on throwing codes. I will only buy OEM now.

Cool, thanks everyone, I thought so. I happen to already have one bosch upstream o2 sensor so I will just get all bosch, they are like $60 a piece on ebay

Not worth replacing the lowers. Just get them and sai coded out.
