How do you change and where is the location of the Knock Sensor on a 1998 Mazda Millenia?

29S HERE, ONLY 97 AND 98 MILLENIAS HAVE THE EXACT SAME MOTORS. I HAVE A 97 AND I HAVE REPLACED MY KNOCK SENSOR WHICH IS LOCATED IN THE CENTER OF THE ENGINE BELOW THE INTAKE. IT WILL REQUIRE THE REMOVAL OF THE AIR INTAKE AND NEW INTAKE GASKETS YOU CANNOT REUSE THE OLD ONES.
