Banks

Ok, to make a long story short, my "Bank 1 Catalyst Effeciency Below Limit" means that my Bank 1 cats are shot so I need to replace them. My question is this: is Bank 1 the side with the air intake box or the battery?

Bank 1 is on the passenger side

That's exactly what I thought, but I figured it'd be best to get assurance be for I ordered the wrong part. Thanks kcm!
