  • Q:

    Your spec tells left side or right side.
    Your explanation: Bank 1-driver side, bank 2-passenger side.
    It depends from what direction to look.

    More specifically:
    Infinity I30 1997, Bank 2 (on the radiator/front side), sensor 1 (before cat).
    Which "direct fit" do I need: left (31.1") or right (37.8")?
    Also, there is a 2-wire sensor, also before cat (?)

    Thank you, Vlad

      I'm glad to assist, Vlad! Bank 1 does not always indicate driver's side and bank 2 does not always indicate passenger side. The part description of left and right will mean driver's and passenger side respectively. This is always as viewed from the driver's seat.

      Bank 1 indicates that the sensor is part of the bank containing cylinder 1. Bank 2 is the opposite bank. On your 1997 Infiniti I30, Bank 1 is located next to the firewall (front of the cabin) and as you stated Bank 2 is closest to the front of the vehicle or radiator. Both Bosch Premium Oxygen Sensors (Part No. 13242 [31.1"] and Part No. 13228 [36.6"]) are intended for use in the upstream left and right banks. To determine which is correct for your vehicle, I suggest measuring the length of the current sensor from the sealing surface to the end of the connector.

  • Q:

    I need to find out where this item is located on the engine. I found bank 1 sensor 1 & replaced it, need to find bank 2 sensor 1. Can you tell me now to locate this?

      The oxygen sensor is located in the Catalytic converter. Most late model cars have two sensors. There will be one at the front of the catalytic converter, and one at the rear. Bank 1 is the drivers side, Bank 2 is the passenger side. Sensor 1 is upstrem, before the cat and sensor 2 is downstream, after the cat.
