Hey guys I am looking to buy some upstream o2 sensors for my PPE header swap, in the event that my existing header o2 sensors break during install.
I found a member selling a Denso #234-4521 o2 Sensor, is this the proper header o2 sensor or is this part number for an exhaust o2 sensor? I want to make sure I get the right ones!
Thanks in advance for the help guys!
