    How are they blowing? Water, carbon, heat, or do you know?

    When you say "blowing" do you mean not reading accurately?
    If so, water is usually the most common reason.

    I'm sure it's water. I had it happening more with the stock exhaust. When I installed the free flow they last longer but still die early.

    I had this happen to the FZR and I noticed a bunch of standing water in my midpipe. So I bet that water is causeing a bunch of steam and taking the senor out. I was advised to run a heat sink bung adapter.

    get the heat sink bung, saves it some exposure. Also start machene first then let sensor heat up as exhaust does so it dosen't get condensation shock
