    It skrews into the block underneath the intake manifold. If you have a Lift it will be very easy to put in.

    It probably got broken off. It's a combination of plastic and metal. Unscrew the metal piece that's probably still there, and then go to a junkyard and find the correct sensor. Most Hondas use the same knock sensor.

    or run an ECU that doesn't check for one.

    I think only VTEC engines came with a knock sensor.

    Sounds about right. He could just put a wrench on his existing one to find out. ;)

    That's true, it does. The S model does not, though.
