My car: 2003 Boxster S.
I want to replace both of these O2 Senors circled in red.
They are the oval plug connector type. Are they both the same unit?
My car has 4 O2 Senors per side and looking at Pelican for O2 Senors with oval plug connectors I get a bit confused as they show 1 Bosch (Before Starter Catalyst, Left or Right).
Then they also show the Bosch (After Starter Catalyst, Left or Right)
So which ones do I want to order to replace both the O2 Senors circled in red??

Thanks!
