    Bummer man. Those are High Dolla not to mention all the work to replace. Hope you figure it out.

    Did you figure it out?

    I’m getting ready to get in there... so I can’t speak from experience. But from what I’ve read the wire and the knock sensors are super fragile because it heats up with the intake. My buddy who gives me advice on work I do to my vehicles told me don’t even touch that wire or the sensors if you don’t have to. They break on their own sometimes.

    I have to change the gasket on my bypass pipe and am going to change the wire harness while I’m in there. I’m hoping my knock sensors aren’t brittle af and don’t break when I try to pull the plugs on them.
