What's the cheapest place to get an oxygen sensor for my 97 GST. I need the once past the cat, the second one back. I know there are universal ones but are those worth it? Also where's the best place any of you have found to get an O.E. one. Thanks for the help. Also if you have an extra second I don't check up on posts too much anymore so if you have good info please email it to me either with the link on the page or at DaBlakNite@hotmail.com
