what?? no. how is it hard to judge which bank is closer to the front bumper, one is close to the front bumper, the other is close to the firewall.
when you pop your hood, look at your engine. see how there are 3 spark plugs in the front and 3 in the back? that is your banks so to speak, if you were to look at your v 6 from the front of the actual engine (your engine sits in the car sideways) each side of the V is a bank
now sensor one will be the one before the cat, and sensor two will be the one after the cat. so you want the o2 sensor that comes off the front bank that is before the cat
