    I'm replacing my cats and think I will put in new 02 sensors to be safe. Can someone tell me the Bosch Part numbers. I found a 13819 & 13820 doing some research. I'm wondering which is the pre-cat and which is downstream? Are these good P/N's?
    Thanks in advance.

    Oh genuine Bosch plug straight in so the new ones i fitted are exactly the same as the ones i took out.
    If you go NGK route then you have to cut the plugs off and splice the wires.

    Good to know! I've always assumed that there would be splicing involved if I changed mine.
