Im kind of over exaggerating with the title. I have a 01 Boxster S with 30k. I recently got a check engine light that read P0153 which is apparently the left pre cat o2 sensor. I bought maxspeed headers and 4 brand new oem bosch o2 sensors and after driving it for a bit maybe couple of hours I get the same check engine light? I think it’s impossible for me to have the same faulty o2 sensor in the exact same spot. What is causing this issue???

Side note: the headers are awesome. I have a stebro exhaust with straight pipes, really changed the sound of the car, also performance gains for sure.
