I may need to replace some O2 sensors and needed your advice on which O2 sensors are teh best. Should I go with Bosch or with Walker products? Walker is a little more expensive but does that mean they are better? I believe the OEM is Bosch but I am not really sure. I know there is a lot of talk about the MAF being a very unreliable product from Bosche and I was wondering if its teh same with oxygen sensors.
