Both upflow and downflow o2 sensors need to be replaced on my '98 base, seen a set online that was priced well but doesn't say if they are upflow/downflow or universal or what. If anyone knows if it doesnt matter please let me know, also my car is a 5 speed-not sure if they make different ones for automatics as well,Thanks

Buy them from there, and you won't have any issues figuring out which ones you need. NTK is the brand you should aim for- they're the OE replacements made by NGK.

NTK or Denso. Whatever you do, don't use Bosch.

Denso looks good, is there any difference in the upflow/downflow sensors besides the length of the plug wire?

Yes, it's a different sensor. Thus, why you need one for each application.
