Where to buy an AEM o2 sensor?

all the different widebands us pretty much two different oxygen sensors with two different connectors. is it a bosch lsu 4.2? is the plug rounded on one side or is it square? Do a search on the internet.
you can buy the stock 02 sensor off of a turbo vw bettle or certain years and models of cadilacs from any auto parts store that will work with your aem.
 
the one from summit looks to be the correct one. right matching part number from aem. the picture on summits website must be wrong. The sensor pictured is not the correct one.
Rectangular plug is different then any thing I have ever had. alot of times it is the same sensor, just a different plug. I am sure their is still a replacement that could be bought at any local auto parts store. Just need to find out what sensor it is and what vehicles it comes stock on.
you could also call ken at push and I am sure he could get you just the 02 sensor.

Hmmmm, my new AEM has the rectangle plug on it. There is some data in the AEM instructions about that plug having a lazer etch resistor inside of it used to "match calibrate" the sensor to the guage.

You may have an older guage???
 
Got mine off ebay for $60 and never had to leave the computer chair.... Works great, fits great... New AEM UEGO A/F gauge with the rectangle plug....
 
AEM calibrates all of their sensors at the factory and then installs resistors inline in order to eliminate the need for free air calibration every so often. Be sure you get the calibrated sensor.

I just threw my innovate LC-1 away. It was still working, but I had heard the AEM's were better. Man if I knew how much better I would have done it a long time ago!
 
I used the same guy as Supraturbo! Highly recommend him, get it at the cheapest price and get a set of bulbs for free... This guy is legit and great, fast service!
 
Does anyone have any ideas on how to keep condensation out? I sealed the back, but still got condensation on the inside of the bezel.

Any help is appreciated.

I had a problem with this as well and water ended up inside, causing it to malfunction. I had to take it apart, dry it out, and now it works fine.

This is what I did, I cut a square piece of freezer baggie (freezer is thicker) out of a sandwich bag, took off the silver screw cap, put the cut plastic over it, then screwed the cap back on, trim the edges.

So far it seems to have sealed it up and it hasn't condensated or gotten wet inside.

This is all I could think of doing.

Hope this helps.
