Where Is The Oxygen Sensor Bank #1, Sensor #1 Located At On A 2004 Hyundai Tiburon GT V6

Asked something similar a few minutes ago, but I wanted to refine it. I need to have the O2 sensor at bank #1, sensor #1 replaced (the mechanic referred to this as “bank #1, side #1”, but I think he meant sensor #1). I just need to know which one it is so I can buy the correct part. What is the location (side of car and before/after catalyst)? Thanks in advance for the info!
Thanks for the answers so far! I have a follow-up though: I noticed that Bosch manufactures universal sensors that seem like they would work well, but I keep seeing “two required” on many of the listings. Do I have to purchase 2 sensors for some reason, or does that refer to something else?
