under intake mani on top of block, toward right rear of motor when you are standing in front of car in wrench-ready position
it's super easy to remove, one elec connector and one bolt.
be aware that the KS is a directional piece, and will not work correctly if not installed at 60-degree angle off centerline of engine. note precise location of the piece you remove, put new one back in exact same location...you'll get fewer CELS after installing the new part!
