Default Are the L and R pre-cat O2 sensors the same?
OxygenSensors.com is showing 2 different part numbers for the DENSOs. The right one is almost $15 more.

One has a slightly longer wire, but most aftermarket suppliers use the same # on both sides.

But if I have extensions I shouldn't need the one w/ the longer wire, correct?

You probably won't even need the extentions. You never know, the longer one might be the cheaper one!

If yes, buy 2 of those.
