1998 A4 2.8L: So my sensor is shoot. I'm looking a Rockauto for the replacement and there a many to select from. My sensor is the square type so I can narrow the search to those. Does anyone have a favorite that they would use? See below. Thanks in advance.

Just changed mine around a week or two ago, I bought the Beck and arnley one from my local auto parts store and it works great

Thanks JKU16. There seems to be two different color sensors. Mine looks to be a dark blue or green. The blue sensors in the pictures seem to be a bright blue. It's a little confusing.

Maybe the previous owner of your A4 changed the sensor on yours before? I'm not so sure but the one I removed from my car was a blue 4 prong square sensor identical to the Beck and arnley one
