watch for the cheapest as it amy not meet oem specs and may not resolve your problem. good advice from matte, take it to a shop and let them handle the whole thing.

I recommend against doing this yourself. Problems with oxygen sensors tend to not be as simple as replace it and move on. Your emissions control system is involved, all the way from the mass airflow sensor to those O2 sensors. You'll save time and frustration by involving a pro.
